Definitions
- the invention relates to the detection diagnosis, and prognosis of uterine cancer.
- the invention relates to the surprising finding that biomarkers corresponding to ACAA1, AP1M2, CGN, DDR1, EFS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNF183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN are differentially expressed in control samples as compared to samples from patients having endometrial cancer and are therefore useful for detecting endometrial cancer.
- these biomarkers having excellent sensitivity, specificity, and/or the ability to separate affected from non affected individuals.
- biomarkers in primary endometrial cancer tumor tissue is correlated to their expression level in uterine fluid samples as compared to control values.
- these biomarkers are robust in that they are found to be differentially expressed in several different types of samples from affected and individuals.
- Endometrial cancer is the most frequent invasive tumors of the female genital tract and the fourth most common in women in western countries ( Jemal et al. (2008) CA Cancer J Clin 58:71-96 ). New methods for the diagnosis, prognosis, and classification of endometrial cancer are needed to combat this deadly disease.
- endometrial cancer is detected early, in its initial stages, by presentation of disease-related symptoms.
- 20% of patients present with myometrial invasion and/or lymph node affectation which are main indicators related to poor prognosis, decrease in survival rate, and more advanced disease.
- the primary therapeutic modality for endometrial cancer is surgical treatment.
- uterine cancer e.g., endometrial cancer
- Uterine cancer usually occurs after menopause.
- Other risk factors for endometrial cancer include being obese, taking estrogen-alone hormone replacement therapy, treatment with tamixofen and having a genetic predisposition to cancer (e.g ., Lynch Syndrome).
- the standard treatment for endometrial cancer varies depending on the stage of the disease. Treatment usually involves surgery to remove the uterus which is called a hysterectomy, although other options include hormone therapy and radiotherapy.
- Methods routinely used in the clinic for diagnosing endometrial cancer include biopsy followed by cytological analysis and/or trans-vaginal ultrasound.
- the diagnosis of endometrial carcinoma is usually done by pathology examination of an endometrial aspirate (20-30%), and by biopsy-guided hysteroscopy (70-80%).
- the rate of success of diagnosis with hysteroscopy is over 90%, with false positives in the case of precursor lesions of the endometrial adenocarcinoma.
- hypoplasias hyperplasias
- endometrial polyps that present a non-negligible degree of malignancy (0-4.8%) and must be removed although asymptomatic or benign appearance; or in the case of diffuse forms of endometrial adenocarcinomas that are difficult to differentiate from an endometrial hyperplasia.
- a less invasive diagnostic test based on molecular markers.
- Such a less invasive test based on molecular markers would allow for more routine screening of uterine cancer.
- a diagnostic test based of molecular markers obtained in a less invasive manner and that has sensitivity and specificity comparable to that of the endometrial biopsy can preclude unnecessary hysteroscopy.
- Endometrial carcinomas can be classified into low grade (type I) and high-grade (type 2).
- Type I endometrioid endometrial cancer (sometimes called estrogen dependent), which represent approximately 80% of new cases, are low grade tumors associated with estrogen stimulation, usually developed in peri- or post-menopausal women and are usually preceded by endometrial hyperplasia with or without atypia.
- Type II non-endometrioid endometrial cancer usually affects older women, are less differentiated and of worse prognosis, not associated with estrogen stimulation, and are related to atrophic endometrium or, occasionally, with endometrial polyps.
- Type I cancers are typically known to have alterations in PTEN, KRAS2, DNA mismatch repair defects, CTNNB1, and have near diploid karyotype.
- Type II cancers typically have TP53 mutations and ErBB2 overexpression and are mostly non-diploid.
- Sugiyama et al. (2003) Clin. Can. Res. 9:5589-5600 ) reported that certain genes are selectively up or down regulated in type I versus type II endometrial cancers. For example, they found that MLH1 was down-regulated in type I cancers as well as other genes related to DNA damage signaling and repair like O 6 -methyl-guanine DNA methyltransferase, DNA polymerase ⁇ catalytic subunit, and Ku (p70/p80) antigen.
- VEGF-C was found to be upregulated in type I cancers at the protein and mRNA level as compared to type II cancers.
- KRAS was found to be upregulated in type II cancers.
- STAT1 was upregulated in type I cancers and STAT2 was upregulated in type II cancers.
- Konecny et al. ((2009) British Journal of Cancer 100, 89-95 ) report that the rate HER2 gene amplification as measured by fluorescence in situ hybridization was greater in type II cancers whereas EGFR expression as measured by IHC techniques was significantly lower in type II cancers.
- Deng et al. ((2005) Clin. Can. Res. vol. 11, no 23:8258-8264 ) report that EIG121 is a marker for type I estrogen associated cancers.
- Uterine cancers are also classified histologically according to cell-type.
- the most common cell-type is referred to endometrioid and represents around 80% of the newly diagnosed cases.
- Other less common uterine cancers are referred to as serous and clear cell carcinomas.
- Most of the type I cancers are of the endometrioid cell-type whereas the type II cancers are more likely to be non-endometrioid uterine cancers.
- Type II cancers are more likely to metastasize and have a poorer prognosis than type I cancers.
- Type I cancers typically have a better prognosis and respond better to therapy.
- CA 125 correlates with tumor size and stage and is an independent predictor of the extrauterine spread.
- WO 98/42865 discloses metalloproteins as markers for endometrial cancer.
- prolactin is a serum biomarker with sensitivity and specificity for endometrial cancer. They found serum CA 125 CA 15-3 and CEA are higher in patients with Stage III disease as compared to stage I. A five-biomarker panel of prolactin, GH, eotaxin, E-selectin, and TSH discriminated endometrial cancer from ovarian and breast cancer.
- transvaginal ultrasound had 100% sensitivity and 60% specificity ( Gull et al. (2003) Am. J. Obstet. Gynecol. 188(2):401-408 ).
- the sensitivity of the endometrial thickness measurement was 17% for a threshold 6 mm and 33% for a threshold of 5 mm ( Fleischer et al. (2001) Am. J. Obstet. Gynecol. 184:70-75 ).
- TVS has a high rate of false positives since other conditions besides Endometrial cancer can produce a thicker endometrium.
- the invention relates to the surprising finding that biomarkers corresponding to ACAA1, AP1M2, CGN, DDR1, EPS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNF183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN are differentially expressed in control samples as compared to samples from patients having endometrial cancer and are therefore useful for detecting endometrial cancer.
- biomarkers having excellent sensitivity, specificity, and/or the ability to separate affected from non affected individuals.
- these biomarkers are robust in that they are found to be differentially expressed in several different types of samples from affected individuals as compared to non-affected individuals.
- the present invention relates to an in vitro diagnostic method for the diagnosis of endometrial cancer comprising detecting the level of the biomarker IKBKE in a sample from a patient, wherein an increased level of the biomarker IKBKE compared to a control value indicates the existence of endometrial cancer.
- the biomarkers of Table 1 were found to be differential expressed between endometrial cancer samples and normal samples as determined by microarray studies (see Table 1 in the Detailed Description of the Invention). The inventors have found that individually each of the biomarkers of Table 1 have predictive value for the diagnosis of endometrial cancer. Furthermore, the levels of combinations of markers of Table 1 have additional predictive value for the diagnosis of endometrial cancer (See Example 5). For example, the inventors have surprisingly found that sub-groups of the biomarkers of Table 1 having from 2-20 biomarkers in various combinations to give fingerprint patterns have excellent predictive value for diagnosis or detection of endometrial cancer.
- biomarkers of Table 1 are differentially expressed in a sample, this increases the likelihood that the individual has endometrial cancer.
- the inventors have also found that addition of other biomarkers besides those listed in Table 1, to the fingerprint pattern also can increase predictive value, and can be useful for classifying endometrial cancers, for differential diagnosis of diseases other than endometrial cancer, and for endometrial cancer prognosis.
- Table 1 lists the ENSEMBL accession numbers for the genes, mRNA, and proteins corresponding to the biomarkers of the invention. Some of the biomarkers have alternative transcripts.
- the invention relates to determining the differential expression of any of these alternative transcripts (or protein isoforms) as long as it expression is correlated with the absence or presence of endometrial cancer.
- Preferred transcripts (or protein isoforms) for detecting endometrial cancer are those which were detected with the array probes as indicated in the Examples.
- the inventors have also found that the markers of Table 1 can be detected in uterine fluid samples and that the level of expression of these markers are correlated in primary tumor and uterine fluid (e.g., obtained by a uterine wash or aspiration).
- the invention therefore provides methods for determining the level of from 1 to 20 of the biomarkers listed in Table 1 in a test sample.
- the method can comprise determining the level of from 1 to 20 of the biomarkers of Table 1 in the test sample from the patient; and comparing the level of the biomarker(s) in the test sample(s) to a control value (e.g., control sample, control value, or control score).
- a control value e.g., control sample, control value, or control score
- a higher level of biomarker(s) which was found to be overexpressed in endometrial cancer as shown in Table 1 in the test sample obtained from the patient compared to the control value indicates endometrial cancer, an increased likelihood of endometrial cancer, and/or a precancerous condition (e.g., endometrial hyperplasia).
- control value e.g ., control sample, control value, and/or control score
- the level of the biomarker(s) can be determined using appropriate assays, including RT-PCR, quantitative PCR, multiplex PCR, Northern hybridization, microarray analysis, two-hybrid assays such as GAL4 DNA binding domain based assays, antibody based assays, EIA, blot assays, sandwich assays, and the like.

Additionally, the inventors surprisingly found that samples obtained from uterine fluid of endometrial cancer patients display expression profiles for the biomarkers listed in Table 1 that were generally correlated to the expression profiles from the primary tumor. Furthermore, a number of the markers found by the inventors are expected to be found on cell surfaces and/or in blood as blood based markers (or in other body fluids like uterine fluid).
- the upregulated biomarkers of Table 1 were shown to be overexpressed at the protein level in primary tissue as compared to normal non-affected tissue.
- the protein level of P4HB by western blot analysis revealed that this biomarker is overexpressed at a protein level as well.
- FIG. 11 through FIG. 16 show overexpression, at the protein level, of AP1M2, IKBKE, EPS8L2, DDR1, CGN, and TJP3.
- P4HB, PPP1R16A and EPS8L2 presented a specific cytoplasmatic expression within the tumoral cells in all carcinoma histological types and grades, and an absence or faint cytoplasmatic staining within the normal epithelial glands as determined by tissue microarray (TMA) immunohistochemistry (IHC).
- TMA tissue microarray
- IHC immunohistochemistry
- the inventors performed gene expression analysis on expression microarrays to detect genes that are differentially expressed in endometrial cancer as compared to normal tissues.
- the gene expression microarray studies disclosed herein revealed that a number of genes in endometrial cancer samples were overexpressed as compared to normal endometrial tissue.
- ACAA1, AP1M2, CGN, DDR1, EPS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNF183, S1RT6, and TJP3, were overexpressed in endometrial cancer samples and EFEMP2, SOCS2, and DCN were underexpressed, as compared to their respective levels in normal endometrial tissue using a microarray experimental strategy.
- Table 1 has the common abbreviation for the gene, the ENSMBL accession numbers (corresponding to the gene, transcript(s), and protein related to the biomarkers of the invention), the fold change values and the p-values for statistical significance.
- Table 1 Differential expression of endometrial cancer biomarkers in primary tumor as compared to control values (obtained from a pool of unaffected tissue, see Example 1).
- markers of Table 1 were also found to be differentially expressed in samples obtained from uterine fluid in patients having endometrial cancer. Markers which were not highly correlated fall off or further away from the correlation line in FIG. 1 .
- the finding of the correlation of expression levels of these biomarkers in primary tissue and uterine fluid was surprising given the heterogeneity of uterine fluid and the findings in the initial microarrays studies. It is believed that this is the first time that that the levels of biomarkers in primary endometrial cancer were shown to be correlated in a statistically significant manner to those found in uterine fluid and therefore this provides a less invasive and more standardized method of screening for endometrial cancer and/or an increased risk of endometrial cancer.
- the disclosure therefore provides a method for diagnosing endometrial cancer and/or an increased likelihood of endometrial cancer by obtaining a uterine fluid sample and determining the level of biomarkers differentially expressed in endometrial cancer as compared to control value.
- the uterine fluid sample is obtained by aspiration. In one aspect, the uterine fluid sample is obtained gently washing and/or rinse the uterine cavity. In one aspect, the level of mRNA is determined. In one aspect, the level of protein is determined. In one aspect, the biomarkers are chosen from the 20 listed in Table 1.
- the p-values for the individual biomarkers in Table 1 as determined in the microarray studies with one sample set were significantly improved upon when the same biomarkers were analyzed by a different technique (quantitative RT-PCR) using a different set of samples, obtained from the patient by a different method.
- the p-values were over 100 fold improved compared to the microarray studies.
- the inventors have found that individually each of the biomarkers of Table 1 have predictive value for the diagnosis of endometrial cancer. Furthermore, combinations of these biomarkers have additional predictive value for the diagnosis of endometrial cancer. For example, the inventors have surprisingly found that numerous subgroups of the biomarkers of Table 1 having from 2-20 biomarkers in various combinations give fingerprint patterns having excellent predictive value for diagnosis or detection of endometrial cancer. Additionally, the inventors have also contemplate that addition of other biomarkers besides those listed in Table 1, to the fingerprint pattern also can increase predictive value, and can be useful for classifying endometrial cancers, for differential diagnosis of diseases other than endometrial cancer, and for endometrial cancer prognosis.
- the present disclosure provides a method for characterizing a sample obtained from a patient for prognostic, diagnostic and/or pharmacogenomic uses.

- Antibodies to the biomarkers of the invention can also be made by using combinatorial libraries to screen for synthetic antibody clones with the desired activity or activities.
- synthetic antibody clones are selected by screening phage libraries containing phage that display various fragments of antibody variable region (Fv) fused to phage coat protein. Such phage libraries are panned by affinity chromatography against the desired antigen. Clones expressing Fv fragments capable of binding to the desired antigen are adsorbed to the antigen and thus separated from the non-binding clones in the library. The binding clones are then eluted from the antigen, and can be further enriched by additional cycles of antigen adsorption/elution.
- Fv antibody variable region
- Antibodies to the biomarkers of the invention can be obtained by designing a suitable antigen screening procedure to select for the phage clone of interest followed by construction of a full length antibody clone using the Fv sequences from the phage clone of interest and suitable constant region (Fc) sequences described in Kabat et al., Sequences of Proteins of Immunological Interest, Fifth Edition, NIH Publication 91-3242, Bethesda MD (1991), vols. 1-3 .

- expression refers to the biosynthesis of a gene product.
- a "cloning vector” is a nucleic acid molecule, for example, a plasmid, cosmid or bacteriophage that has the capability of replicating autonomously in a host cell.
- Cloning vectors typically contain (i) one or a small number of restriction endonuclease recognition sites at which foreign DNA sequences can be inserted in a determinable fashion without loss of an essential biological function of the vector, and (ii) a marker gene that is suitable for use in the identification and selection of cells transformed or transfected with the cloning vector. Marker genes include, but are not limited to, genes that provide tetracycline resistance or ampicillin resistance..
- An "expression vector” is a nucleic acid construct, generated recombinantly or synthetically, bearing a series of specified nucleic acid elements that enable transcription of a particular gene in a host cell. Typically, gene expression is placed under the control of certain regulatory elements, including constitutive or inducible promoters, tissue-preferred regulatory elements, and enhancers.
- a "recombinant host” may be any prokaryotic or eukaryotic cell that contains either a cloning vector or expression vector. This term also includes those prokaryotic or eukaryotic cells that have been genetically engineered to contain the cloned gene(s) in the chromosome or genome of the host cell.
- operably linked is used to describe the connection between regulatory elements and a gene or its coding region. That is, gene expression is typically placed under the control of certain regulatory elements, including constitutive or inducible promoters, tissue-specific regulatory elements, and enhancers. Such a gene or coding region is said to be “operably linked to” or “operatively linked to” or “operably associated with” the regulatory elements, meaning that the gene or coding region is controlled or influenced by the regulatory element.
- Sequence homology is used to describe the sequence relationships between two or more nucleic acids, polynucleotides, proteins, or polypeptides, and is understood in the context of and in conjunction with the terms including: (a) reference sequence, (b) comparison window, (c) sequence identity, (d) percentage of sequence identity, and (e) substantial identity or “homologous.”
- a "reference sequence” is a defined sequence used as a basis for sequence comparison.
- a reference sequence may be a subset of or the entirety of a specified sequence; for example, a segment of a full-length cDNA or gene sequence, or the complete cDNA or gene sequence.
- the length of the reference polypeptide sequence can be chosen from at least about 16 amino acids, at least about 20 amino acids, at least about 25 amino acids, and about 35 amino acids, about 50 amino acids, or about 100 amino acids.
- the length of the reference nucleic acid sequence can be chosen from at least about 50 nucleotides, at least about 60 nucleotides, at least about 75 nucleotides, and about 100 nucleotides or about 300 nucleotides or any integer thereabout or there between.
- a “comparison window” includes reference to a contiguous and specified segment of a polynucleotide sequence, wherein the polynucleotide sequence may be compared to a reference sequence and wherein the portion of the polynucleotide sequence in the comparison window may comprise additions, substitutions, or deletions ( i.e ., gaps) compared to the reference sequence (which does not comprise additions, substitutions, or deletions) for optimal alignment of the two sequences.
- the comparison window is at least 20 contiguous nucleotides in length, and optionally can be 30, 40, 50, 100, or longer.
- Optimal alignment of sequences for comparison may be conducted by the local homology algorithm of Smith and Waterman (1981) Adv. Appl. Math., 2: 482 ,; by the homology alignment algorithm of Needleman and Wunsch (1970) J. Mol. Biol., 48: 443 ; by the search for similarity method of Pearson and Lipman (1988) Proc. Natl. Acad. Sci.
- the BLAST family of programs which can be used for database similarity searches includes: BLASTN for nucleotide query sequences against nucleotide database sequences; BLASTX for nucleotide query sequences against protein database sequences; BLASTP for protein query sequences against protein database sequences; TBLASTN for protein query sequences against nucleotide database sequences; and TBLASTX for nucleotide query sequences against nucleotide database sequences.
- sequence identity/similarity values refer to the value obtained using the BLAST 2.0 suite of programs, or their successors, using default parameters. Altschul et al. (1997) Nucleic Acids Res, 2:3389-3402 . It is to be understood that default settings of these parameters can be readily changed as needed in the future.
- BLAST searches assume that proteins can be modeled as random sequences. However, many real proteins comprise regions of nonrandom sequences which may be homopolymeric tracts, short-period repeats, or regions enriched in one or more amino acids. Such low-complexity regions may be aligned between unrelated proteins even though other regions of the protein are entirely dissimilar.
- a number of low-complexity filter programs can be employed to reduce such low-complexity alignments. For example, the SEG ( Wooten and Federhen, (1993) Comput. Chem. 17:149-163 ) and XNU ( Claverie and States (1993) Comput. Chem., 17:191-1 ) low-complexity filters can be employed alone or in combination.
- Sequence identity in the context of two nucleic acid or polypeptide sequences includes reference to the residues in the two sequences which are the same when aligned for maximum correspondence over a specified comparison window, and can take into consideration additions, deletions and substitutions.
- percentage of sequence identity is used in reference to proteins it is recognized that residue positions which are not identical often differ by conservative amino acid substitutions, where amino acid residues are substituted for other amino acid residues with similar chemical properties (for example, charge or hydrophobicity) and therefore do not deleteriously change the functional properties of the molecule.
- sequences differ in conservative substitutions the percent sequence identity may be adjusted upwards to correct for the conservative nature of the substitution. Sequences which differ by such conservative substitutions are said to have sequence similarity.
- Percentage of sequence identity means the value determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotide sequence in the comparison window may comprise additions, substitutions, or deletions ( i . e ., gaps) as compared to the reference sequence (which does not comprise additions, substitutions, or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity.
- substantially identical or “homologous” in their various grammatical forms in the context of polynucleotides means that a polynucleotide comprises a sequence that has a desired identity, for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%, compared to a reference sequence using one of the alignment programs described using standard parameters.
- a desired identity for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%, compared to a reference sequence using one of the alignment programs described using standard parameters.
- a desired identity for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%.
- nucleotide sequences are substantially identical if two molecules hybridize to each other under stringent conditions. However, nucleic acids which do not hybridize to each other under stringent conditions are still substantially identical if the polypeptides which they encode are substantially identical. This may occur, for example, when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code.
- One indication that two nucleic acid sequences are substantially identical is that the polypeptide which the first nucleic acid encodes is immunologically cross reactive with the polypeptide encoded by the second nucleic acid, although such cross-reactivity is not required for two polypeptides to be deemed substantially identical.
- substantially identical or “homologous” in their various grammatical forms in the context of peptides indicates that a peptide comprises a sequence that has a desired identity, for example, at least 60% identity, preferably at least 70% sequence identity to a reference sequence, more preferably 80%, still more preferably 85%, even more preferably at least 90% or 95% sequence identity to the reference sequence over a specified comparison window.
- a desired identity for example, at least 60% identity, preferably at least 70% sequence identity to a reference sequence, more preferably 80%, still more preferably 85%, even more preferably at least 90% or 95% sequence identity to the reference sequence over a specified comparison window.
- optimal alignment is conducted using the homology alignment algorithm of Needleman and Wunsch (1970) J. Mol. Biol., 48:443 .
- peptide sequences are substantially identical.
- a peptide is substantially identical to a second peptide, for example, where the two peptides differ only by a conservative substitution.
- Peptides which are "substantially similar" share sequences as noted above except that residue positions which are not identical may differ by conservative amino acid changes.

- useful labels include radioactive isotopes, magnetic beads, metallic beads, colloidal particles, fluorescent dyes, electron-dense reagents, enzymes (for example, as commonly used in an ELISA), biotin, digoxigenin, or haptens.
- a "labeled nucleic acid or oligonucleotide probe” is one that is bound, either covalently, through a linker or a chemical bond, or noncovalently, through ionic bonds, van der Waals forces, electrostatic attractions, hydrophobic interactions, or hydrogen bonds, to a label such that the presence of the nucleic acid or probe may be detected by detecting the presence of the label bound to the nucleic acid or probe.
- nucleic acid or oligonucleotide probe is defined as a nucleic acid capable of binding to a target nucleic acid of complementary sequence through one or more types of chemical bonds, usually through complementary base pairing, usually through hydrogen bond formation.
- a probe may include natural (i.e ., A, G, C, or T) or modified bases (7-deazaguanosine, inosine, etc .).
- the bases in a probe may be joined by a linkage other than a phosphodiester bond, so long as it does not unduly interfere with hybridization.
- probes may bind target sequences lacking complete complementarity with the probe sequence depending upon the stringency of the hybridization conditions.
- the probes are preferably directly labeled with isotopes, for example, chromophores, lumiphores, chromogens, or indirectly labeled with biotin to which a streptavidin complex may later bind.
- isotopes for example, chromophores, lumiphores, chromogens, or indirectly labeled with biotin to which a streptavidin complex may later bind.
- the phrase "selectively (or specifically) hybridizes to” refers to the binding, duplexing, or hybridizing of a molecule only to a particular nucleotide sequence under stringent hybridization conditions when that sequence is present in a complex mixture (for example, total cellular or library DNA or RNA).
- stringent hybridization conditions refers to conditions under which a probe will hybridize to its target complementary sequence, typically in a complex mixture of nucleic acids, but to no other sequences. Stringent conditions are sequence-dependent and circumstance-dependent; for example, longer sequences can hybridize with specificity at higher temperatures.
- hybridizes under stringent conditions is intended to describe conditions for hybridization and washing under which nucleotide sequences at least 60% homologous to each other typically remain hybridized to each other.
- the conditions are such that sequences at least about 65%, more preferably at least about 70%, and even more preferably at least about 75% or more homologous to each other typically remain hybridized to each other.
- stringent conditions are selected to be about 5 to 10 C lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength pH.
- Tm is the temperature (under defined ionic strength, pH, and nucleic concentration) at which 50% of the probes complementary to the target hybridize to the target sequence at equilibrium (as the target sequences are present in excess, at Tm, 50% of the probes are occupied at equilibrium).
- Stringent conditions will be those in which the salt concentration is less than about 1.0 M sodium ion, typically about 0.01 to 1.0 M sodium ion concentration (or other salts) at pH 7.0 to 8.3 and the temperature is at least about 30 C for short probes (for example, 10 to 50 nucleotides) and at least about 60 C for long probes (for example, greater than 50 nucleotides). Stringent conditions also may be achieved with the addition of destabilizing agents, for example, formamide. For selective or specific hybridization, a positive signal is at least two times background, preferably 10 times background hybridization.
- Exemplary stringent hybridization conditions can be as following, for example: 50% formamide, 5xSSC and 1% SDS, incubating at 42 C, or 5xSSC and 1% SDS, incubating at 65 C., with wash in 0.2xSSC and 0.1% SDS at 65 C.
- Alternative conditions include, for example, conditions at least as stringent as hybridization at 68 C for 20 hours, followed by washing in 2xSSC, 0.1% SDS, twice for 30 minutes at 55 C and three times for 15 minutes at 60 C.
- Another alternative set of conditions is hybridization in 6xSSC at about 45 C, followed by one or more washes in 0.2xSSC, 0.1% SDS at 50-65 C.
- a temperature of about 36 C is typical for low stringency amplification, although annealing temperatures may vary between about 32 C and 48 C depending on primer length.
- a temperature of about 62 C is typical, although high stringency annealing temperatures can range from about 50 C to about 65 C, depending on the primer length and specificity.
- Typical cycle conditions for both high and low stringency amplifications include a denaturation phase of 90 C to 95 C for 30 sec. to 2 min., an annealing phase lasting 30 sec. to 2 min., and an extension phase of about 72 C for 1 to 2 min.
- Nucleic acids that do not hybridize to each other under stringent conditions can still be substantially identical if the polypeptides which they encode are substantially identical. This occurs, for example, when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. In such cases, the nucleic acids typically hybridize under moderately stringent hybridization conditions.
- Exemplary "moderately stringent hybridization conditions" include a hybridization in a buffer of 40% formamide, 1 M NaCl, 1% SDS at 37 C, and a wash in 1xSSC at 45 C. A positive hybridization is at least twice background. Those of ordinary skill will readily recognize that alternative hybridization and wash conditions can be utilized to provide conditions of similar stringency.
- target gene or “target biomarker” or “target nucleic acid” or “target protein” can refer to a target nucleic acid (DNA and RNA) or protein (or polypeptide), ( e . g ., corresponding to the biomarkers in Table 1) and can include their polymorphic variants, alleles, mutants, and interspecies homologs that have (i) substantial nucleotide sequence homology (for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%) with the nucleotides sequence indicated in Ensembl database for the indicated ID number; or (ii) at least 65% sequence homology with the amino acid sequence as indicated in the Ensembl record; or (iii) substantial nucleotide sequence homology (for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%) with the nucle

- the target genes/biomarker can have numerous splice forms and variants. When referring to a specific target gene or locus by a reference number (e.g., Entrez gene ID or Ensembl), all splices forms and variant which are included in the various embodiments of the invention.
- the target gene/biomarker can also comprise a regulatory element. These sequences are representative of one particular individual in the population of humans.
- allelic variants Humans vary from one to another in their gene sequences. These variations are very minimal, sometimes occurring at a frequency of about 1 to 10 nucleotides per gene. Different forms of any particular gene exist within the human population. These different forms are called allelic variants. Allelic variants often do not change the amino acid sequence of the encoded protein; such variants are termed synonymous. Even if they do change the encoded amino acid (non-synonymous), the function of the protein is not typically affected. Such changes are evolutionarily or functionally neutral. When a gene ID (e.g., genbank or Ensembl) is referred to in the present application all allelic variants are intended to be encompassed by the term. The gene ID sequences given for a biomarker are provided merely as representative examples of a wild-type human sequence. The invention is not limited to a single allelic form of the amplified genes or regions (and proteins they encode).

- the mean fold change or M values can be ranked based on their probability of being different from 0, according to the absolute value of the regularized t-statistic (Baldi and Long, 2001) which uses a Bayesian framework to derive a modified and improved t-student statistics.
- the mean M distribution was used. This distribution is adjusted to a normal distribution and an iterative process is used to define the mean M numbers that are outside the distribution.
- the cut-off is chosen as n times the Standard deviations ( ⁇ ) from the mean. This method generates a robust mean and standard deviation and allows to dynamically adjusting the cut-off value to the noise distribution of the data.
- values with mean FC>3 ⁇ or mean FC ⁇ -3 ⁇ of the sample data distribution were selected.
- Candidate genes were selected as biomarkers for endometrial cancer based on fold overexpression, p-value, and other factors. Table 1 in the Detailed Description of the Invention shows 17 overexpressed genes and 3 genes underexpresssed identified using these procedures. The overexpression of these genes was validated by RT-PCR as described in the next examples.
- Table 1 shows the common abbreviation used for the gene, the ENSMBL gene, transcript and protein accession numbers along with the fold overexpression and calculated p-values.
- Endometrial aspirates were collected with the help of a Cornier pipelle, after complete informed consent was obtained from all patients.
- the aspirate (uterine fluid) was immediately transferred to an eppendorf tube containing 500 microliters of a RNA preserving solution (RNA later, Ambion).
- the sample was centrifuged and the pellet containing a representative population of cells from the uterine cavity was further processed for RNA extraction (Qiagen). Quality tests (Bioanalyzer) were performed before the analysis of gene expression by Taqman technology for the selected markers of endometrial carcinoma.
- biomarkers from primary tumor sample and uterine fluid sample obtained by the procedure of Example 2 were compared as by RT-PCR following the general RT-PCR protocol as described in Example 4.
- the biomarkers in this study included ACAA1, AP1M2, CGN, DDR1, EPS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNA183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN whose expression level was found to be surprisingly correlated between the primary tumor and endometrial aspirates (uterine fluid). See Figure 1 .

- uterine fluid can be used to assess biomarkers for endometrial cancer.
- biomarkers for endometrial cancer For example, prognostic biomarkers for endometrial cancer, biomarkers for staging endometrial cancer, biomarkers for determining the type of endometrial cancer (e . g ., Type 1 vs. Type II) or type (endometrioid, clear cell, serrous, etc. ), auxiliary diagnostic biomarkers, differential diagnosis biomarkers, can be assayed in uterine fluid to characterize the cancer.
- Microfluidic Cards from Applied Biosystems were used to perform RT-PCR with RNA isolated from tumor and normal Endometrial tissue samples. In this case both types of tissues, healthy and carcinogenic were obtained from the same patient by microdissection procedures. These studies confirmed the microarray results for most of the markers of Table 1.
- Another set of RT-PCT studies were performed using aspirates obtained from endometrial cancer patients (confirmed) and aspirates from non-affected individuals. These studies using aspirates samples are described in more detail below.
- Microfluidic Card contains Applied Biosystems fluorogenic 5' nuclease assays that detect the real-time amplification of the array selected targets. Relative levels of gene expression are determined from the fluorescence data generated during PCR using the ABI PRISM® 7900HT Sequence Detection System (7900HT SDS) Relative Quantification software.
- Samples from 24 patients not having endometrial cancer ("controls" or "normal”). These were a heterogeneous mix of samples some of them from patients with other non-tumoral pathologies liked polyps: 4 samples from patients with atrophic endometriod, 4 normal samples, two from patients having polyps from post-menopausical women and 11 samples from pre-menopausical women (7 of them in secretory phase and 4 in proliferative phase of the cycle). See Tables below for a summary of samples.
- RNA samples were isolated from aspirate samples following the procedure above described and a quality control was performed previously to final sample selection. Aspirate samples were collected as described in Example 2.
- RT-PCR was performed following Applied Biosystem standard protocol for the 7900HT system.
- the protocol consisted in a two-step method where the first step is the generation of cDNA from the RNA samples using a High Capacity cDNA Kit and the second step is the amplification of cDNA, once loaded in the MFC, by the ABI PRISM® 7900 HT system.
- RT-PCR data were collected for a set of 20 genes identified in Example 1 and quantified relative to POLR2A levels.
- the RQ values for the aspirates corresponding to the 30 tumor samples and the 24 samples that were not endometrial cancer (normals) are illustrated in a box and whiskers plot, see Figure 2A and 2B .
- Table 2 in the Detailed Description of the Invention gives a summary of the mean RQ values, standard error of the mean and p-values calculated for these markers in this sample set.
- the p-values obtained using the control sample set in the microarray studies (Table 1) were significantly improved in a different sample set using different techniques (microarray versus RT-PCR) and different sources of sample (aspirates versus primary tumor). In most cases the p-value improved over 100-fold for the biomarkers. This is related in part to the robust nature of the microarray experimental design and robust selection of markers based on the Inventors' criteria.
- the next table shows the sensitivity and specificity for each individual gene on the patent application and the area under de ROC (AUROC) curve for each gene when comparing the RQ values from the 30 tumour samples and the 24 control samples.
- a support vector machine (SVM) program was used to calculate the data.

- the AUROC values for these biomarkers indicate that these markers are very useful for diagnosis of endometrial cancer.
- Table 6 Sensitivity, Specificity and AUROC values for the biomarkers of the invention determined from aspirates samples in affected (endometrial cancer) and non-affected individuals.
- Control samples were a heterogeneous group with pre and post-menopausical women. At the same time, aspirates from pre-menopausical women could be divided in two categories depending of the uterine endometrial cycle phase they were when the sample was taken: proliferative or secretory. The characterization of secretory versus proliferative phase patients was accomplished by a pathologist using standard techniques.
- the area ROC for each comparison was calculated using the GraphPad Prism program and anova test was applied to see if the differences among these groups were significant.
- genes like P4HB or SOCS2, which separate the tumour samples from the control independently of the nature of the control samples (post-menopausical, pre-menopausical in secretory or in proliferative).
- Other genes like P2RX4 or PPFIBP2, could distinguish between a tumour sample (affected) and a sample in secretory phase better as compared to controls from postmenopausical women.
- a primary modality for screening for endometrial problems is the trans-vaginal ultrasound which is used to estimate endometrial thickness where patients having a thicker endometrium (over a certain threshold) are likely to have endometrial cancer or another disease or condition. Endometrium thickness also varies as a function of the phase of the menstrual with individuals in secretory phase having a thicker endometrium as compared to individuals in proliferative phase.

- RQ relative quantity, it is the relative amount of RNA for a specific gene present on the tumours samples referred to the amount present on the control sample for the same gene.
- a number of endogenous genes can be used as a control for normalization as well as other controls for normalization.
- a preferred endogenous gene has the following characteristics: it is a gene constitutively expressed in the same tissue under different circumstances like for example cancer development. So it could be used to normalize differences in the amount of cDNA when loading the samples or variations due to experimental reasons for the qRT-PCR.
- a support vector machine based algorithm was used to identify combinations of markers of Table 1 that are useful for predicting endometrial cancer and/or an increased likelihood of having endometrial cancer.
- the publically available program DTREG program was used to analyze the data (see the www at DTREG.COM).
- Support vector machine algorithm can be used for many applications including identifying gene expression profiles for separating populations having different phenotypic characteristics.
- the idea behind the algorithm is a multidimensional representation of the data, e.g., each marker is plotted on a different dimension and a plane is sought though this multidimensional representation of the data that can separate the phenotypes.
- the plan through the "middle" is referred to as the separating hyperplane and represents a solution: answers (e.g., expression level over a given threshold value) that fall on one side of the line fall into one category ( e.g., cancer) and answers ( e.g., expression level over a given threshold value) that follow on the other side of the line correspond to the other category ( e.g., no cancer).
- This maximum margin hyperplane is the one that separates the two groups and adopts the maximal distance from any one of the given expression profiles.
- sensitivity , specificity and AUROC genes combined two to two, three to three, four to four, five to five, six to six, seven to seven and all of them together. See the Table below for a summary of the data.

- the first combination is able to classify all the samples correctly but the percentage of some healthy samples of having cancer are very close to 50%: some cancer samples are too close to be misclassified when using this combination.
- the risk of misclassifying cancer patients with a false diagnosis is not able to classify correctly all the cancer patients and they do it with a higher percentage of risk of cancer than the previous combination. For that reason these combinations are valuable from a clinical point of view.

- Example 5 shows that TJP3 can be combined with other biomarkers to give excellent predictive power for diagnosis of endometrial cancer.
- TJP3 (ZO-3) was first identified as a 130 kDa protein that coimmunoprecipitates with ZO-1. It is a member of the MAGUK proteins (MEMBRANE-associated guanylate kinase-like homologues). These proteins are implicated in the formation and maintenance of supramolecular complexes at specific areas of the cell surface called tight junctions. Tight junctions locate at the most apical part of lateral membranes of simple epithelial cells, and are considered to be involved in barrier and fence functions.
- MAGUK proteins Cloning and sequencing cDNAs encoding MAGUK proteins showed that all have three PDZ domains (PDZ1 to -3), one SH3 domain, and one guanylate kinase-like (GUK) domain in this order from their NH2 termini (PMID: 10966866). Among these domains, PDZ domains bind to COOH-terminal ends of various proteins, especially integral membrane proteins, most of which end in valine. Thus, MAGUKs can cross-link multiple integral membrane proteins at the cytoplasmic surface of plasma membranes to establish specialized membrane domains. ZO-3 has also been reported to associate with ZO-1, but not with ZO-2, although the domains responsible for ZO-3/ZO-1 interaction remain unidentified. ZO-3 was also shown to directly bind to the cytoplasmic domain of occludin (Haskins et al. 1998).

Description
- The invention relates to the detection diagnosis, and prognosis of uterine cancer. The invention relates to the surprising finding that biomarkers corresponding to ACAA1, AP1M2, CGN, DDR1, EFS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNF183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN are differentially expressed in control samples as compared to samples from patients having endometrial cancer and are therefore useful for detecting endometrial cancer. In particular these biomarkers having excellent sensitivity, specificity, and/or the ability to separate affected from non affected individuals. Furthermore, the inventors found that the differential expression of these biomarkers in primary endometrial cancer tumor tissue is correlated to their expression level in uterine fluid samples as compared to control values. Thus these biomarkers are robust in that they are found to be differentially expressed in several different types of samples from affected and individuals.
- Each year in Europe there are about 150,000 new cases of endometrial cancer and about 46,000 women die from the disease (Ferlay et al. (2007) Ann. Onc. 18:581-592). In the United States, about 41,000 new case of endometrial carcinoma are diagnosed per year and 7,300 women die each year (see American Cancer Society statistics available on the internet). The incidence and death rate from endometrial cancer are increasing.
- Endometrial cancer (EC) is the most frequent invasive tumors of the female genital tract and the fourth most common in women in western countries (Jemal et al. (2008) CA Cancer J Clin 58:71-96). New methods for the diagnosis, prognosis, and classification of endometrial cancer are needed to combat this deadly disease.
- Often endometrial cancer is detected early, in its initial stages, by presentation of disease-related symptoms. Unfortunately, 20% of patients present with myometrial invasion and/or lymph node affectation, which are main indicators related to poor prognosis, decrease in survival rate, and more advanced disease. The primary therapeutic modality for endometrial cancer is surgical treatment.
- Common symptoms of uterine cancer (e.g., endometrial cancer) include unusual vaginal bleeding or discharge, trouble urinating, pelvic pain, and pain during intercourse. Uterine cancer usually occurs after menopause. Other risk factors for endometrial cancer include being obese, taking estrogen-alone hormone replacement therapy, treatment with tamixofen and having a genetic predisposition to cancer (e.g., Lynch Syndrome). The standard treatment for endometrial cancer varies depending on the stage of the disease. Treatment usually involves surgery to remove the uterus which is called a hysterectomy, although other options include hormone therapy and radiotherapy.
- Methods routinely used in the clinic for diagnosing endometrial cancer include biopsy followed by cytological analysis and/or trans-vaginal ultrasound. The diagnosis of endometrial carcinoma is usually done by pathology examination of an endometrial aspirate (20-30%), and by biopsy-guided hysteroscopy (70-80%). The rate of success of diagnosis with hysteroscopy is over 90%, with false positives in the case of precursor lesions of the endometrial adenocarcinoma. (hyperplasias); endometrial polyps, that present a non-negligible degree of malignancy (0-4.8%) and must be removed although asymptomatic or benign appearance; or in the case of diffuse forms of endometrial adenocarcinomas that are difficult to differentiate from an endometrial hyperplasia. Thus, there is a need for a less invasive diagnostic test based on molecular markers. Such a less invasive test based on molecular markers would allow for more routine screening of uterine cancer. A diagnostic test based of molecular markers obtained in a less invasive manner and that has sensitivity and specificity comparable to that of the endometrial biopsy can preclude unnecessary hysteroscopy.
- Endometrial carcinomas can be classified into low grade (type I) and high-grade (type 2). Type I endometrioid endometrial cancer (sometimes called estrogen dependent), which represent approximately 80% of new cases, are low grade tumors associated with estrogen stimulation, usually developed in peri- or post-menopausal women and are usually preceded by endometrial hyperplasia with or without atypia. Type II non-endometrioid endometrial cancer usually affects older women, are less differentiated and of worse prognosis, not associated with estrogen stimulation, and are related to atrophic endometrium or, occasionally, with endometrial polyps.
- Type I cancers are typically known to have alterations in PTEN, KRAS2, DNA mismatch repair defects, CTNNB1, and have near diploid karyotype. Type II cancers typically have TP53 mutations and ErBB2 overexpression and are mostly non-diploid. Sugiyama et al. ((2003) Clin. Can. Res. 9:5589-5600) reported that certain genes are selectively up or down regulated in type I versus type II endometrial cancers. For example, they found that MLH1 was down-regulated in type I cancers as well as other genes related to DNA damage signaling and repair like O6-methyl-guanine DNA methyltransferase, DNA polymerase α catalytic subunit, and Ku (p70/p80) antigen. VEGF-C was found to be upregulated in type I cancers at the protein and mRNA level as compared to type II cancers. KRAS was found to be upregulated in type II cancers. STAT1 was upregulated in type I cancers and STAT2 was upregulated in type II cancers. Konecny et al. ((2009) British Journal of Cancer 100, 89-95) report that the rate HER2 gene amplification as measured by fluorescence in situ hybridization was greater in type II cancers whereas EGFR expression as measured by IHC techniques was significantly lower in type II cancers. Deng et al. ((2005) Clin. Can. Res. vol. 11, no 23:8258-8264) report that EIG121 is a marker for type I estrogen associated cancers.
- Uterine cancers are also classified histologically according to cell-type. The most common cell-type is referred to endometrioid and represents around 80% of the newly diagnosed cases. Other less common uterine cancers are referred to as serous and clear cell carcinomas. Most of the type I cancers are of the endometrioid cell-type whereas the type II cancers are more likely to be non-endometrioid uterine cancers. Type II cancers are more likely to metastasize and have a poorer prognosis than type I cancers. Type I cancers typically have a better prognosis and respond better to therapy.
- A number of studies have examined gene-expression profiles for classifying uterine cancers. Sugiyama et al. ((2003) Clin. Canc. Res. 9:5589-5600) report that between the type I and II cancers 45 gene were highly expressed in type I cancers and 24 highly expressed in type I cancers. Risinger et al. ((2003) Canc. Res. 63:6-11) report that microarray analysis of different histologic subtypes of endometrial cancer have distinct gene expression profiles. They found that 191 genes exhibited greater than 2-fold difference in expression between endometrioid and non-endometrioid endometrial cancers.
- A number of endometrial cancer biomarkers for endometrial cancer have been identified. Elevated levels of CA 125, CA 15-3, and CA 19-9 are associated with shorter survival time. CA 125 correlates with tumor size and stage and is an independent predictor of the extrauterine spread.
-
WO 98/42865 - Serum markers for the detection of uterine cancer have been reported in the literature. Yurkovetsky et al. ((2007) Gyn. Onc. 107:58-65) identified that prolactin is a serum biomarker with sensitivity and specificity for endometrial cancer. They found serum CA 125 CA 15-3 and CEA are higher in patients with Stage III disease as compared to stage I. A five-biomarker panel of prolactin, GH, eotaxin, E-selectin, and TSH discriminated endometrial cancer from ovarian and breast cancer.
- Another important issue for clinicians for diagnosis of endometrial cancer relates to synchronous cancers. Guirguis et al. (Gyn. Onc. (2008) 108:370-376) have reported that 10% of ovarian cancer patients have a tumor in the endometrium and 5-25% of patients with endometrial cancer also have a tumor in the ovary. Determining the primary site of a cancer has important treatment implications. Stage III endometrial carcinoma is treated with surgery followed by chemotherapy and/or radiation; while dual primary stage I ovarian and endometrial cancers have a better prognosis and may not require adjuvant therapy.
- Current methods of diagnosing endometrial cancer often create discomfort to the patient and sometimes rely on subjective interpretation of visual images. There is a need for less invasive methods of screening for endometrial cancer which are less subjective in interpretation. In addition there is a need for new markers that are useful for the early detection of endometrial cancer. Current methods for detecting endometrial cancer include the dilation and curettage method which is considered the gold standard, but this method is invasive, can cause significant discomfort, and may require a trained pathologist for interpretation, and therefore is not suitable as a general screening tool. Another less invasive method for diagnosing endometrial cancer involves transvaginal ultrasound which measures the thickness of the endometrium. In a study of patients having post-menopausal bleeding, using a cutoff of 4 mm, it was found that transvaginal ultrasound had 100% sensitivity and 60% specificity (Gull et al. (2003) Am. J. Obstet. Gynecol. 188(2):401-408). In women without vaginal bleeding, the sensitivity of the endometrial thickness measurement was 17% for a threshold 6 mm and 33% for a threshold of 5 mm (Fleischer et al. (2001) Am. J. Obstet. Gynecol. 184:70-75). TVS has a high rate of false positives since other conditions besides Endometrial cancer can produce a thicker endometrium. One potential problem with the use of TVS in pre- and peri-menopausal women is that the thickness of the endometrium varies as a function of the phase of the menstrual cycle. Furthermore, women taking tamoxifen also have thicker endometrium. Therefore there is a need for techniques and markers that can complement and/or improve the ability of TVS in the diagnosis of Endometrial cancer.
- Cleary there is room for improvement in the tools currently available for screening for endometrial cancer.
- The invention relates to the surprising finding that biomarkers corresponding to ACAA1, AP1M2, CGN, DDR1, EPS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNF183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN are differentially expressed in control samples as compared to samples from patients having endometrial cancer and are therefore useful for detecting endometrial cancer. In particular these biomarkers having excellent sensitivity, specificity, and/or the ability to separate affected from non affected individuals. Furthermore, the inventors found that the differential expression of these biomarkers in primary endometrial cancer tumor tissue is correlated to their expression level in uterine fluid samples as compared to control values. Thus, these biomarkers are robust in that they are found to be differentially expressed in several different types of samples from affected individuals as compared to non-affected individuals.
- Accordingly, the present invention relates to an in vitro diagnostic method for the diagnosis of endometrial cancer comprising detecting the level of the biomarker IKBKE in a sample from a patient, wherein an increased level of the biomarker IKBKE compared to a control value indicates the existence of endometrial cancer.
- The biomarkers of Table 1 were found to be differential expressed between endometrial cancer samples and normal samples as determined by microarray studies (see Table 1 in the Detailed Description of the Invention). The inventors have found that individually each of the biomarkers of Table 1 have predictive value for the diagnosis of endometrial cancer. Furthermore, the levels of combinations of markers of Table 1 have additional predictive value for the diagnosis of endometrial cancer (See Example 5). For example, the inventors have surprisingly found that sub-groups of the biomarkers of Table 1 having from 2-20 biomarkers in various combinations to give fingerprint patterns have excellent predictive value for diagnosis or detection of endometrial cancer. Generally, if more than one of the biomarkers of Table 1 are differentially expressed in a sample, this increases the likelihood that the individual has endometrial cancer. Moreover, the inventors have also found that addition of other biomarkers besides those listed in Table 1, to the fingerprint pattern also can increase predictive value, and can be useful for classifying endometrial cancers, for differential diagnosis of diseases other than endometrial cancer, and for endometrial cancer prognosis. Table 1 lists the ENSEMBL accession numbers for the genes, mRNA, and proteins corresponding to the biomarkers of the invention. Some of the biomarkers have alternative transcripts. The invention relates to determining the differential expression of any of these alternative transcripts (or protein isoforms) as long as it expression is correlated with the absence or presence of endometrial cancer. Preferred transcripts (or protein isoforms) for detecting endometrial cancer are those which were detected with the array probes as indicated in the Examples.
- The inventors have also found that the markers of Table 1 can be detected in uterine fluid samples and that the level of expression of these markers are correlated in primary tumor and uterine fluid (e.g., obtained by a uterine wash or aspiration).
- The invention therefore provides methods for determining the level of from 1 to 20 of the biomarkers listed in Table 1 in a test sample. The method can comprise determining the level of from 1 to 20 of the biomarkers of Table 1 in the test sample from the patient; and comparing the level of the biomarker(s) in the test sample(s) to a control value (e.g., control sample, control value, or control score). A higher level of biomarker(s) which was found to be overexpressed in endometrial cancer as shown in Table 1 in the test sample obtained from the patient compared to the control value (e.g., control sample, control value, and/or control score) indicates endometrial cancer, an increased likelihood of endometrial cancer, and/or a precancerous condition (e.g., endometrial hyperplasia). A lower level of biomarker(s) which was found to be underexpressed in endometrial cancer as shown in Table 1 in the test sample obtained from the patient compared to level in the control value (e.g., control sample, control value, and/or control score) indicates endometrial cancer, an increased likelihood of endometrial cancer, and/or a precancerous condition (e.g., endometrial hyperlasia). The level of the biomarker(s) can be determined using appropriate assays, including RT-PCR, quantitative PCR, multiplex PCR, Northern hybridization, microarray analysis, two-hybrid assays such as GAL4 DNA binding domain based assays, antibody based assays, EIA, blot assays, sandwich assays, and the like. The level of the biomarkers of Table 1 can be determined in body fluids and tissues for the diagnosis of endometrial cancer. The level of the biomarkers of Table 1 can be determined in tumor tissue obtained by biopsy for example. The level of the biomarkers of Table 1 can be determined in samples obtained from uterine aspirates and/or fluid. The level of the biomarkers of Table 1 can be determined in blood, serum, or plasma.
- The biomarkers of Table 1 include ACAA1, AP1M2, CGN, DDR1, EPS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNF183, SIRT6, and TJP3, which were found to be upregulated in endometrial cancer and DCN, SOCS2, and EFEMP2 which were found to be down regulated in endometrial cancer in these studies. The biomarkers for use in the method of the invention for detecting endometrial cancer or an increased likelihood of endometrial cancer include from 1 to 17 of the upregulated biomarkers listed in Table 1 and from 1 to 3 of the downregulated markers listed in Table 1.

According to one aspect, the level of mRNA corresponding to the biomarker is determined. According to another aspect, the level of protein corresponding to the biomarker is determined.
- Amongst the biomarkers of Table 1, the levels of CGN, P4HB, PPP1R16A, IKBKE, RASSF7, RNF183, and TJP3, were found to have the highest mean level of overexpression in the RT-PCR studies as compared to their expression in normal samples (e.g., not having endometrial cancer). Thus, given that the RT-PCR experiments demonstrated a high level of overexpression in a statistically significant manner (all p-values are less than 0.0001 for the sample set studied) for these markers, they represent preferred markers for diagnosis of endometrial cancer and/or an increased likelihood of having endometrial cancer. Therefore, the levels of CGN, P4HB, PPP1R16A, IKBKE, RASSF7, RNF183, and TJP3 are excellent predictors of endometrial cancer and/or an increased likelihood of having endometrial cancer. The levels of these markers are less likely to give a false positive as compared to other markers whose expression levels are not as high and/or as significant.

- Amongst the biomarkers of Table 1, the level of some biomarkers were found to be able to differentiate samples from patients having cancer as compared to normal samples (or control) and samples from patients in the secretory phase of the menstrual cycle.

These biomarkers therefore represent endometrial cancer biomarkers. Additionally, the inventors surprisingly found that samples obtained from uterine fluid of endometrial cancer patients display expression profiles for the biomarkers listed in Table 1 that were generally correlated to the expression profiles from the primary tumor. Furthermore, a number of the markers found by the inventors are expected to be found on cell surfaces and/or in blood as blood based markers (or in other body fluids like uterine fluid). As shown in Example 6, the upregulated biomarkers of Table 1 were shown to be overexpressed at the protein level in primary tissue as compared to normal non-affected tissue. For example, the protein level of P4HB by western blot analysis, revealed that this biomarker is overexpressed at a protein level as well.

Furthermore, P4HB, PPP1R16A and EPS8L2 presented a specific cytoplasmatic expression within the tumoral cells in all carcinoma histological types and grades, and an absence or faint cytoplasmatic staining within the normal epithelial glands as determined by tissue microarray (TMA) immunohistochemistry (IHC). - These studies provide endometrial cancer diagnostic biomarkers with excellent predictive value, alone or in combinations, that may be detected using methods which are less invasive as compared to the current standard of care. Furthermore, the inventors have identified specific subsets of biomarkers that are capable of distinguishing, in endometrial aspirates samples, endometrial cancer affected patients from different sub-groups of non-affected patients.
- Several of the studies used to identify (expression microarray) and validate (RT-PCR) the biomarkers of the invention are described briefly below and in more detail in the Example section.

In general the p-values were over 100 fold improved compared to the microarray studies.
- The inventors have found that individually each of the biomarkers of Table 1 have predictive value for the diagnosis of endometrial cancer. Furthermore, combinations of these biomarkers have additional predictive value for the diagnosis of endometrial cancer. For example, the inventors have surprisingly found that numerous subgroups of the biomarkers of Table 1 having from 2-20 biomarkers in various combinations give fingerprint patterns having excellent predictive value for diagnosis or detection of endometrial cancer. Additionally, the inventors have also contemplate that addition of other biomarkers besides those listed in Table 1, to the fingerprint pattern also can increase predictive value, and can be useful for classifying endometrial cancers, for differential diagnosis of diseases other than endometrial cancer, and for endometrial cancer prognosis.

- "Auxiliary biomarkers" refer to biomarkers that can be used in conjunction with the one or more biomarkers of Table 1. The auxiliary biomarkers can be used in the methods of the invention to provide further characterization of a disease or condition a patient may have.
- Differential diagnosis biomarkers are useful for distinguishing between diseases that may present with similar clinical symptoms. For example, a patient may have symptoms of endometrial cancer (e.g., vaginal bleeding and/or pelvic pain) but these symptoms can also be caused by different diseases (e.g., ovarian cancer). Therefore, the differential diagnosis biomarkers provide information for characterization a disease. Examples of diseases that may present similar symptoms as endometrial cancer include uterine fibroids, endometriosis, endometrial hyperplasia, uterine sarcoma - another type of uterus cancer, uterine leiomyomas, endometrial polyp (type of polyps), cervical cancer, atrophic endometrium, adenomyosis, atrophic vaginitis, ovarian tumour, leiomyosarcoma, and endometrial proliferation.
- According to the inventors' finding that the level of biomarkers in primary endometrial cancer tissue can be correlated to their levels in uterine fluid, it is contemplated that uterine fluid samples can be used for differential diagnosis of conditions other than endometrial cancer. Thus, in one aspect, the invention provides a method for the differential diagnosis of endometrial cancer by obtaining a uterine fluid sample from a patient and determining the level of one or more biomarkers that are capable of distinguishing endometrial cancer from non-endometrial cancer. Differential diagnosis biomarkers for endometriosis are useful for distinguishing endometriosis from endometrial cancer. Differential diagnosis biomarkers for ovarian cancer are useful for distinguishing ovarian cancer from endometrial cancer. Examples of biomarkers useful for distinguishing endometrial cancer from ovarian cancer include, but are not limited to, those described in Yurkovetsky et al. (Gyn, Onc. (2007) 107:58-65) where they reported a five-biomarker panel of prolactin, GH, eotaxin, E-selectin, and TSH for discriminating endometrial cancer from ovarian and breast cancer.
- A number of endometrial cancer biomarkers have been identified. CA 125 correlates with tumor size and stage and is an independent predictor of the extrauterine spread. Serum markers for the detection of uterine cancer have been reported in the literature.
- Prognosis biomarkers: Elevated levels of CA 125, CA 15-3, and CA 19-9 are associated with shorter survival time. They found serum CA 125 CA 15-3 and CEA are higher in patients with Stage III disease as compared to stage I. Another group of prognostic markers include estrogen receptor; progesterone receptor, and HER2.
- Biomarkers for classifying endometrial cancer include those for estimating stage of the cancer, cell-type, and/or type of endometrial cancer (e.g., type I verus type II). Examples of biomarkers for classifying endometrial cancer include, but are not limited to, those described in Sugiyama et al. (2003) Clin. Can. Res. 9:5589-5600. Genes showing higher expression in type I as compared to type II include MMP11, RHOG, and platelet-derived growth factor B subunit precursor, START2, octamer-binding transcription factor 1, and Data-6, growth factor VEGF-C precursor, caspase (caspase I/IL-1 β converting enzyme). Genes showing higher expression in type II as compared to type I included PIRIN, EGR1, STAT1, IFN regulatory factor 1, and OKRAS. Konecny et al. ((2009) Brutish Journal of ) report that the rate HER2 gene amplification as measured by fluorescence in situ hybridization was greater in type II cancers whereas EGFR expression as measured by IHC techniques was significantly lower in type II cancers. Deng et al. ((2005) Clin. Can. Res. vol. 11, no 23:8258-8264) report that EIG121 is a marker for type I estrogen associated cancers. Markers for classifying endometrial cancer can also be used to distinguish different histological types of endometrial cancer like serous and endometrioid cancers. Risinger et at. ((2003) Canc. Res. 63:6-11) identified biomarkers that could distinguish papillary serous cancers from endometrioid cancers. For example AGR2, TFF3, DUSP6, IGF2, FOLR1, and UCHL1 were found to be differentially expressed between papillary serous and endometrioid cancers as found by microarray and validated by RT-PCR. AGR2, TFF3, DUSP6 were found to be upregulated in endometrioid type cancers whereas IGF2, FOLR1 and UCHL1 were found to be upregulated in papillary serous cancers.
- According to the inventor's finding that the level of biomarkers in primary endometrial cancer tissue can be correlated to their levels in uterine fluid, it is contemplated that uterine fluid samples can be used to classify the type of endometrial cancer. Classifying the type of endometrial cancer can refer to distinguishing type I and type II cancers. Classifying the type of endometrial cancer can also refer to determining the histological type and/or sub-type of endometrial cancer. Thus, in one aspect, the invention provides a method for classifying an endometrial cancer by obtaining a uterine fluid sample from a patient and determining the level of one or more biomarkers that are capable of classifying an endometrial cancer.
- "Auxiliary biomarkers for detecting endometrial cancer" refer to biomarkers that can be used in addition to the biomarkers of Table 1 for the diagnosis of endometrial cancer and/or an increased risk of having endometrial cancer: Yurkovetsky et al. (Gyn. Onc. (2007) 107:58-65) identified that prolactin is a serum biomarker with sensitivity and specificity for endometrial cancer. Yurkovetsky et al. found that prolactin, GH, eotaxin, E-selectin, and TSH were useful markers for diagnosising endometrial cancer.
In some aspects of these embodiments, one or more auxiliary biomarkers are examined for alterations in a sample from a patient suspected of having endometrial cancer. In a specific aspect, the auxiliary biomarkers are chosen from serum biomarkers. In a more specific aspect the serum biomarkers are one or more proteins chosen from CA 125, CA 15-3, CA 19-9, CEA, AFP, CA 72-4, VEGF, bFGF, IGFBPI, HGF, ErbB2, EGFR, TGF α, Fas, FasL, Cyfra 21-1, MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-12, MMP-13, tPAI, sICAM, sVCAM, sE-selectin, adiponectin, resistin, IL-6, IL-8, TNF α, TNFR I, G-CSF, CD40L, IL-2R, IP-10, MCP-1, MIP-1α, MIP-1β, MIF, eotaxin, RANTES, FSH, LH, TSH, ACTH, Prolactin, GH, βHCG. hK8, hK10, active PAI-1, ULBP-1, ULBP-2, ULBP-3, MICA, angiostatin, SCC, serum amyloid A, TTR, S100, mesothelin, and myeloperoxidase (MPO). In a more specific aspect, the serum biomarkers are chosen from prolactin, GH, eotaxin, e-selectin and FSH. In an even more specific aspect, the serum biomarker is prolactin. In some aspects, the auxiliary biomarker(s) can be examined in uterine aspirates (e.g., mRNA level and/or protein levels). - The invention, in some embodiments, relates to characterizing one or more biomarkers of Table 1, from a sample from a patient suspected of having endometrial cancer or desiring screening for cancer. Examples of such samples that can be used in the invention are fluid, tissue samples, and/or cells. Depending on the specific marker, the methods used for characterizing the biomarkers of the invention can include e.g., examining the DNA copy number of the gene corresponding to the biomarker, detecting the protein related to the biomarker, determining the mRNA expression levels of the biomarker, etc. The invention is useful for a number of applications including diagnosis, prognosis, staging, predicting response to therapy. The inventors have found evidence of differential expression of the biomarkers of Table I in a number of different samples including mRNA in primary tumor, protein in primary tumor, and mRNA in aspirates, and protein in aspirates. The biomarkers of Table 1 include those that are overexpressed in samples from endometrial cancer patients as compared to normal levels. Additionally some of the biomarkers of Table 1 are underexpressed in samples from endometrial cancer patients as compared to normal levels
- The invention, in some embodiments, relates to characterizing one or more of the biomarkers of Table 1, from a patient sample (e.g., tumor, cancer cell, sample suspected of being cancer, body fluid (e.g., uterine fluid), blood, serum, plasma, and vaginal blood/discharge) and/or from a "normal" cell, from an individual (or alternatively a control value can be used in lieu of the normal value from the cell).
- In one aspect, the sample to be analyzed is obtained from a patient that has risk factors for endometrial cancer. Risk factors for endometrial cancer include, but are not limited to, having Lynch Syndrome, being genetically related to a person having Lynch Syndrome, obese, taking estrogen-alone hormone replacement therapy, and prior treatment with tamixofen.
- In one aspect of this embodiment, the sample is analyzed is a uterine fluid sample. In one aspect, the sample is that is used is obtained by using a soft, straw-like device (pipelle) to suction off a small sample of lining from the uterus. In one aspect, the sample is obtained by using a sharp-edged tool called a curette by scraping a small sample and collect it with a syringe or suction (e.g., dilation and curettage). In one aspect, the sample is obtained by using an electronic suction device (e.g., Vabra aspiration). In one aspect, the sample is obtained by using a spray of liquid (jet irrigation) to wash off some of the tissue that lines the uterus. In some aspects, a brush may be used to remove some of the lining before the washing is done.
- In one embodiment, the sample for analyzing the biomarkers is obtained using a syringe or pipelle type device. In one embodiment, the device for collection of the uterine fluid sample from an internal cavity (e.g., uterus) of a patient, comprises a barrel having an opening at one end thereof, a plunger operable axially within the barrel, the barrel and the plunger defining a fluid chamber having a volume which varies on axial movement of the plunger within the barrel, and a hollow, elongate tube extending from the fluid chamber through the opening in the barrel, the tube being in operative engagement with the plunger for axial movement to extend and retract the tube within respect to the barrel on axial movement of the plunger, and the tube being in fluid communication with the fluid chamber to provide a fluid flow path to and from the fluid chamber through the hollow tube. In one aspect of this embodiment, after the sample is obtained using the device, it is stored in an agent that preserves the integrity of the biomarker of interest. For example, when the biomarker being analyzed is a nucleic acid like RNA, the sample can be stored in an agent that prevents degradation of RNA molecules in the sample, or of the biomarker is a protein the sample can be stored e.g., in an agent that preserves protein. Example of agents that prevent degradation of RNA molecules in a sample are RNase inhibitors (e.g., RNeasy from Qiagen, SUPERase-In™ from Ambion or ScriptGuard™ RNase Inhibitor from epicenter biotechnologies) or molecules that precipitate RNA out of biological solutions (e.g., triphenylmethane dyes (e.g., methyl green, crystal violet, and pararosaniline), cresyl violet, polyamines, and cobalt ions). Example of agents that prevent the degradation of protein is protease inhibitors (e.g.. PMSF (phenylmethanesulfonyl fluoride, Complete protease inhibitor cocktail from Roche, or Pepstatin) or agents that fix tissues (formalin).
- Thus the invention provides in one embodiment, an in vitro diagnostic method for endometrial cancer comprising determining the level of the biomarker IKBKE in a uterine fluid aspirate sample from a patient having a symptom or risk factor for endometrial cancer, wherein the biomarker IKBKE is differentially expressed in endometrial cancer as compared to control values representative of individuals not affected by endometrial cancer, wherein if the level of the biomarker IKBKE is upregulated in the endometrial aspirate sample from the patient then the patient has an increased likelihood of having endometrial cancer.

- Quantitative PCR In some embodiments, the invention relies on quantitative PCR to determine the level of one or more biomarkers of Table 1. In a specific aspect the quantitative PCR method is quantitative RT-PCR. The methods can be semi-quantitative or fully quantitative.
- The methods of the invention for detecting the biomarkers of the invention can comprise competitive quantitative PCR or real-time quantitative PCR which both estimate target gene concentration in a sample by comparison with standard curves constructed from amplifications of serial dilutions of standard DNA. Quantitative PCR or real-time quantitative PCR differ substantially in how the standard curves are generated. In competitive QPCR, an internal competitor DNA is added at a known concentration to both serially diluted standard samples and unknown (e.g., obtained from a patient) samples. After coamplification, ratios of the internal competitor and target PCR products are calculated for both standard dilutions and unknown samples, and a standard curve is constructed that plots competitor-target PCR product ratios against the initial target DNA concentration of the standard dilutions. Given equal amplification efficiency of competitor and target DNA, the concentration of the latter in patient samples can be extrapolated from this standard curve.
- In real-time QPCR, the accumulation of amplification product is measured continuously in both standard dilutions of target DNA and samples containing unknown amounts of target DNA. A standard curve is constructed by correlating initial template concentration in the standard samples with the number of PCR cycles (Ct) necessary to produce a specific threshold concentration of product. In the test samples, target PCR product accumulation is measured after the same Ct, which allows interpolation of target DNA concentration from the standard curve. Although real-time QPCR permits more rapid and facile measurement of target DNA during routine analyses, competitive QPCR remains an important alternative for target quantification in environmental samples. The coamplification of a known amount of competitor DNA with target DNA is an intuitive way to correct for sample-to-sample variation of amplification efficiency due to the presence of inhibitory substrates and large amounts of background DNA that are obviously absent from the standard dilutions.
- Another type of QPCR is applied quantitatively PCR. Often termed "relative quantitative PCR," this method determines the relative concentrations of specific nucleic acids. In the context of the present invention, RT-PCR is performed on mRNA species isolated from patients. By determining that the concentration of a specific mRNA species, it can be determined if the gene encoding the specific mRNA species is differentially expressed.

- Diagnostic antibodies to one or more of the biomarkers of Table 1 (also referred to as a target protein) for diagnostic uses can be obtained in any number of ways. Furthermore, antibodies to some of the biomarkers of Table 1 are commercially available or described in the literature. These known antibodies can be used in the methods of the invention and/or as the basis of engineering new antibodies. Phage display techniques can be used to generate antibodies to one or more of the biomarkers of Table 1. Standard hybridoma technologies can be used to generate antibodies to one or more of the biomarkers of Table 1. Antibodies to some of the biomarkers of Table 1 are known in the art see the examples. In some aspects, the antibody to one or more of the biomarkers of Table 1 is derived from an animal source (e.g., mouse, rat, or rabbit).
- The target protein antibodies may comprise polyclonal antibodies. Methods of preparing polyclonal antibodies are known to the skilled artisan. Polyclonal antibodies can be raised in a mammal, for example, by one or more injections of an immunizing agent and, if desired, an adjuvant. Typically, the immunizing agent and/or adjuvant t will be injected in the mammal by multiple subcutaneous or intraperitoneal injections. The immunizing agent may include the target protein polypeptide (or fragment thereof) or a fusion protein thereof. It may be useful to conjugate the immunizing agent to a protein known to be immunogenic in the mammal being immunized. Examples of such immunogenic proteins include but are not limited to keyhole limpet hemocyanin, serum albumin, bovine thyroglobulin, and soybean trypsin inhibitor. Examples of adjuvants which may be employed include Freund's complete adjuvant and M PL-TDM adjuvant (monophosphoryl Lipid A, synthetic trehalose dicorynomycolate). The immunization protocol may be selected by one skilled in the art without undue experimentation.
- The target protein antibodies may, alternatively, be monoclonal antibodies. Monoclonal antibodies may be prepared using hybridoma methods, such as those described by Kohler and Milstein (1975) Nature 256:495. In a hybridoma method, a mouse, hamster, or other appropriate host animal, is typically immunized with an immunizing agent to elicit lymphocytes that produce or are capable of producing antibodies that will specifically bind to the immunizing agent. Alternatively, the lymphocytes may be immunized in vitro.
- The immunizing agent will typically include the target protein polypeptide (or fragment thereof) or a fusion protein thereof. Generally, either peripheral blood lymphocytes ("PBLs") are used if cells of human origin are desired, or spleen cells or lymph node cells are used if non-human mammalian sources are desired. The lymphocytes are then fused with an immortalized cell line using a suitable fusing agent, such as polyethylene glycol, to form a hybridoma cell (Goding, Monoclonal Antibodies: Principles and Practice, Academic Press, (1986) pp. 59-103). Immortalized cell lines are usually transformed mammalian cells, particularly myeloma cells of rodent, bovine and human origin. Usually, rat or mouse myeloma cell lines are employed. The hybridoma cells may be cultured in a suitable culture medium that preferably contains one or more substances that inhibit the growth or survival of the unfused, immortalized cells. For example, if the parental cells lack the enzyme hypoxanthine guanine phosphoribosyl transferase (HGPRT or HPRT), the culture medium for the hybridomas typically will include hypoxanthine, aminopterin, and thymidine ("HAT medium"), which substances prevent the growth of HGPRT-deficient cells.
- Preferred immortalized cell lines are those that fuse efficiently, support stable high level expression of antibody by the selected antibody-producing cells, and are sensitive to a medium such as HAT medium. More preferred immortalized cell lines are murine myeloma lines, which can be obtained, for instance, from the Salk Institute Cell Distribution Center, San Diego, Calif. and the American Type Culture Collection, Manassas, Va. Human myeloma and mouse-human heteromyeloma cell lines also have been described for the production of human monoclonal antibodies (Kozbor (1984) J. Immunol. 133:3001; Brodeur et al., Monoclonal Antibody Production Techniques and Applications, Marcel Dekker, Inc., New York, (1987) pp. 51-63).
- The culture medium in which the hybridoma cells are cultured can then be assayed for the presence of monoclonal antibodies directed against target protein. Preferably, the binding specificity of monoclonal antibodies produced by the hybridoma cells is determined by immunoprecipitation or by an in vitro binding assay, such as radioimmunoassay (RIA) or enzyme-linked immunoabsorbent assay (ELISA). Such techniques and assays are known in the art. The binding affinity of the monoclonal antibody can, for example, be determined by the Scatchard analysis of Munson and Pollard (1980) Anal. Biochem. 107:220.
- After the desired hybridoma cells are identified, the clones may be subcloned by limiting dilution procedures and grown by standard methods [Monoclonal Antibodies: Principles and Practice, Academic Press, (1986) pp. 59-103]. Suitable culture media for this purpose include, for example, Dulbecco's Modified Eagle's Medium and RPMI-1640 medium. Alternatively, the hybridoma cells may be grown in vivo as ascites in a mammal.
- The monoclonal antibodies secreted by the subclones may be isolated or purified from the culture medium or ascites fluid by conventional immunoglobulin purification procedures such as, for example, protein A-Sepharose, hydroxylapatite chromatography, gel electrophoresis, dialysis, or affinity chromatography.
- The monoclonal antibodies may also be made by recombinant DNA methods, such as those described in
U.S. Pat. No. 4,816,567 . DNA encoding the monoclonal antibodies of the invention can be readily isolated and sequenced using conventional procedures (e.g., by using oligonucleotide probes that are capable of binding specifically to genes encoding the heavy and light chains of murine antibodies). The hybridoma cells of the invention serve as a preferred source of such DNA. Once isolated, the DNA may be placed into expression vectors, which are then transfected into host cells such as simian COS cells, Chinese hamster ovary (CHO) cells, or myeloma cells that do not otherwise produce immunoglobulin protein, to obtain the synthesis of monoclonal antibodies in the recombinant host cells. The DNA also may be modified, for example, by substituting the coding sequence for human heavy and light chain constant domains in place of the homologous murine sequences [U.S. Pat. No. 4,816,567; Morrison et al. , supra] or by covalently joining to the immunoglobulin coding sequence all or part of the coding sequence for a non-immunoglobulin polypeptide. Such a non-immunoglobulin polypeptide can be substituted for the constant domains of an antibody of the invention, or can be substituted for the variable domains of one antigen-combining site of an antibody of the invention to create a chimeric bivalent antibody. - The antibodies may be monovalent antibodies. Methods for preparing monovalent antibodies are well known in the art. For example, one method involves recombinant expression of immunoglobulin light chain and modified heavy chain. The heavy chain is truncated generally at any point in the Fc region so as to prevent heavy chain crosslinking. Alternatively, the relevant cysteine residues are substituted with another amino acid residue or are deleted so as to prevent crosslinking.
- In vitro methods are also suitable for preparing monovalent antibodies. Digestion of antibodies to produce fragments thereof, particularly, Fab fragments, can be accomplished using routine techniques known in the art.
- Antibodies to the biomarkers of the invention can also be made by using combinatorial libraries to screen for synthetic antibody clones with the desired activity or activities. In principle, synthetic antibody clones are selected by screening phage libraries containing phage that display various fragments of antibody variable region (Fv) fused to phage coat protein. Such phage libraries are panned by affinity chromatography against the desired antigen. Clones expressing Fv fragments capable of binding to the desired antigen are adsorbed to the antigen and thus separated from the non-binding clones in the library. The binding clones are then eluted from the antigen, and can be further enriched by additional cycles of antigen adsorption/elution. Antibodies to the biomarkers of the invention can be obtained by designing a suitable antigen screening procedure to select for the phage clone of interest followed by construction of a full length antibody clone using the Fv sequences from the phage clone of interest and suitable constant region (Fc) sequences described in Kabat et al., Sequences of Proteins of Immunological Interest, Fifth Edition, NIH Publication 91-3242, Bethesda MD (1991), vols. 1-3.
- The antibodies (and fragments thereof) of the invention can be conjugated to molecules for diagnostic purposes. For example, an antibody to a biomarker of Table 1 can be conjugated to a detectable label (e.g., for imaging purposes) for diagnosing or detecting endometrial cancer. Suitable detectable markers include, but are not limited to, a radioisotope, a nanoparticle, a fluorescent compound, a bioluminescent compound, chemiluminescent compound, a metal chelator or an enzyme. Techniques for conjugating diagnostic agents to antibodies are well known (Holmes et al. (2001) Curr Protoc Cytom. May; Chapter 4:Unit 4.2; Kumar et al (2008) ACS Nano. Mar;2(3):449-56; Rosenthal et al. (2006) Laryngoscope Sep;116(9):1636-41). Additionally kits for conjugating agents to diagnostic antibodies are commercially available.

The area under the ROC, or AUROC, curve can range from 0 to 1. An area under the ROC curve of 1 is a perfect test or separation of groups while an area under the ROC of 0.5 indicates that the classifier is essentially unable to separate the groups and is therefore not useful.
- A "cancer" in an animal refers to the presence of cells possessing characteristics typical of cancer-causing cells, for example, uncontrolled proliferation, loss of specialized functions, immortality, significant metastatic potential, significant increase in anti-apoptotic activity, rapid growth and proliferation rate, and certain characteristic morphology and cellular markers.

"Detecting a cancer" also can refer to obtaining evidence regarding the likelihood of the presence of precancerous or cancerous cells in the animal or assessing the predisposition of a patient to the development of a cancer. Detecting a cancer can be accomplished using the methods of this invention alone, in combination with other methods, or in light of other information regarding the state of health of the animal.
- A "tumor," as used herein, refers to all neoplastic cell growth and proliferation, whether malignant or benign, and all precancerous and cancerous cells and tissues.
- The term "precancerous" refers to cells or tissues having characteristics relating to changes that may lead to malignancy or cancer.
- In general, a "gene" is a region on the genome that is capable of being transcribed to an RNA that either has a regulatory function, a catalytic function, and/or encodes a protein. An eukaryotic gene typically has introns and exons, which may organize to produce different RNA splice variants that encode alternative versions of a mature protein. The skilled artisan will appreciate that the present invention encompasses all encoding transcripts that may be found, including splice variants, allelic variants and transcripts that occur because of alternative promoter sites or alternative polyadenylation sites of the biomarkers as listed in Table 1. A "full-length" gene or RNA therefore encompasses any naturally occurring splice variants, allelic variants, other alternative transcripts, splice variants generated by recombinant technologies which bear the same function as the naturally occurring variants, and the resulting RNA molecules. A "fragment" of a gene, including an oncogene, can be any portion from the gene, which may or may not represent a functional domain, for example, a catalytic domain, a DNA binding domain, etc. A fragment may preferably include nucleotide sequences that encode for at least 25 contiguous amino acids, and preferably at least about 30, 40, 50, 60, 65, 70, 75 or more contiguous amino acids or any integer thereabout or therebetween. In some aspects of the invention, the skilled artisan recognizes that the term gene is used interchangeably with the term "locus", which refers more generically to a region of genomic DNA regardless if it codes for RNA, protein, or a regulatory element.
- A "differentially expressed gene transcript", as used herein, refers to a gene, transcript that is found at a different level in different cell or tissue types of an organism having a tumor or cancer, compared to the level or state off the gene transcript found in the cells of the same tissue in a healthy organism, or in the cells of the same tissue in the same organism. Multiple copies of gene transcripts may be found in an organism having the tumor or cancer, while fewer copies of the same gene transcript are found in a healthy organism or healthy cells of the same tissue in the same organism, or vice-versa for underexpressed genes. In general, differentially expressed transcripts are those which when measured in an affected sample or sample from an affected patient have a detectably different level of expression as compared to a control value which is representative of a non-affected sample or sample from a non-affected patient. Examples of differential expression include a change of 10% or more, 20% or more 30% or more, 40% or more, or 50% or more in affected as compared to non-affected.
- As used herein the term "polypeptide" means a sequence of amino acids joined together by peptide bonds. The amino acid sequence of the polypeptide can determined by the sequence of the DNA bases which encode the amino acids of the polypeptide chain. The polypeptides described herein include, but are not limited to, complete proteins, fragments of complete proteins, epitopes of proteins etc. As used herein the term polypeptide, peptide, and protein refer to molecule having two or more amino acid residues (natural or unnatural) joined together by one or more peptide bonds.
- A "differentially expressed gene," can be a target, fingerprint, or pathway gene. For example, a "fingerprint gene", as used herein, refers to a differentially expressed gene whose expression pattern can be used as a prognostic or diagnostic marker for the evaluation of tumors and cancers, or which can be used to identify compounds useful for the treatment of tumors and cancers, for example, endometrial cancer.
- Fingerprint genes can be one or more genes (or corresponding biomarkers e.g., protein) corresponding to the biomarkers of Table 1.
- A "fingerprint pattern", as used herein, refers to a pattern generated when the expression pattern of a series (which can range from two up to all the fingerprint genes that exist for a given state) of fingerprint genes is determined. A fingerprint pattern also may be referred to as n "profile". A fingerprint pattern or expression profile having from 1 to 20 of the biomarkers of Table 1 can be used in the same diagnostic, prognostic, and methods of the invention.
- "Pathway genes", as used herein, are genes that encode proteins or polypeptides that interact with other gene products involved in tumors and cancers. Pathway genes also can exhibit target gene and/or fingerprint gene characteristics.
- A "detectable" RNA expression level, as used herein, means a level that is detectable by standard techniques currently known in the art or those that become standard at some future time, and include for example, differential display, RT (reverse transcriptase)-coupled polymerase chain reaction (PCR), Northern Blot, and/or RNase protection analyses.
- The nucleic acid molecules to be used in accordance with the invention, for example, those corresponding to IKBKE or more biomarkers of Table 1, and its subsequences/alternative transcripts, can be inserted into a vector, as described below, which will facilitate expression of the insert. The nucleic acid molecules and the polypeptides they encode can be used directly as diagnostic agents, or can be used (directly in the case of the polypeptide or indirectly in the case of a nucleic acid molecule) to generate antibodies that, in turn, are clinically useful as a diagnostic agent. Accordingly, vectors containing the nucleic acids to be used in in accordance with the invention, cells transfected with these vectors, the polypeptides expressed, and antibodies generated against either the entire polypeptide or an antigenic fragment thereof, are among the aspects of the invention.
- An "isolated DNA molecule" is a fragment of DNA that has been separated from the chromosomal or genomic DNA of an organism. Isolation also is defined to connote a degree of separation from original source or surroundings.
- "Complementary DNA" (cDNA), often referred to as "copy DNA", is a single-stranded DNA molecule that is formed from an mRNA template by the enzyme reverse transcriptase. Those skilled in the art also use the term "cDNA" to refer to a double-stranded DNA molecule that comprises such a single-stranded DNA molecule and its complement DNA strand.
- The term "expression" refers to the biosynthesis of a gene product.
- A "cloning vector" is a nucleic acid molecule, for example, a plasmid, cosmid or bacteriophage that has the capability of replicating autonomously in a host cell. Cloning vectors typically contain (i) one or a small number of restriction endonuclease recognition sites at which foreign DNA sequences can be inserted in a determinable fashion without loss of an essential biological function of the vector, and (ii) a marker gene that is suitable for use in the identification and selection of cells transformed or transfected with the cloning vector. Marker genes include, but are not limited to, genes that provide tetracycline resistance or ampicillin resistance..
- An "expression vector" is a nucleic acid construct, generated recombinantly or synthetically, bearing a series of specified nucleic acid elements that enable transcription of a particular gene in a host cell. Typically, gene expression is placed under the control of certain regulatory elements, including constitutive or inducible promoters, tissue-preferred regulatory elements, and enhancers.
- A "recombinant host" may be any prokaryotic or eukaryotic cell that contains either a cloning vector or expression vector. This term also includes those prokaryotic or eukaryotic cells that have been genetically engineered to contain the cloned gene(s) in the chromosome or genome of the host cell.
- The term "operably linked" is used to describe the connection between regulatory elements and a gene or its coding region. That is, gene expression is typically placed under the control of certain regulatory elements, including constitutive or inducible promoters, tissue-specific regulatory elements, and enhancers. Such a gene or coding region is said to be "operably linked to" or "operatively linked to" or "operably associated with" the regulatory elements, meaning that the gene or coding region is controlled or influenced by the regulatory element.
- "Sequence homology" is used to describe the sequence relationships between two or more nucleic acids, polynucleotides, proteins, or polypeptides, and is understood in the context of and in conjunction with the terms including: (a) reference sequence, (b) comparison window, (c) sequence identity, (d) percentage of sequence identity, and (e) substantial identity or "homologous."
- A "reference sequence" is a defined sequence used as a basis for sequence comparison. A reference sequence may be a subset of or the entirety of a specified sequence; for example, a segment of a full-length cDNA or gene sequence, or the complete cDNA or gene sequence. For polypeptides, the length of the reference polypeptide sequence can be chosen from at least about 16 amino acids, at least about 20 amino acids, at least about 25 amino acids, and about 35 amino acids, about 50 amino acids, or about 100 amino acids. For nucleic acids, the length of the reference nucleic acid sequence can be chosen from at least about 50 nucleotides, at least about 60 nucleotides, at least about 75 nucleotides, and about 100 nucleotides or about 300 nucleotides or any integer thereabout or there between.
- A "comparison window" includes reference to a contiguous and specified segment of a polynucleotide sequence, wherein the polynucleotide sequence may be compared to a reference sequence and wherein the portion of the polynucleotide sequence in the comparison window may comprise additions, substitutions, or deletions (i.e., gaps) compared to the reference sequence (which does not comprise additions, substitutions, or deletions) for optimal alignment of the two sequences. Generally, the comparison window is at least 20 contiguous nucleotides in length, and optionally can be 30, 40, 50, 100, or longer. Those of skill in the art understand that to avoid a misleadingly high similarity to a reference sequence due to inclusion of gaps in the polynucleotide sequence a gap penalty is typically introduced and is subtracted from the number of matches.
- Methods of alignment of sequences for comparison are well-known in the art. Optimal alignment of sequences for comparison may be conducted by the local homology algorithm of Smith and Waterman (1981) Adv. Appl. Math., 2: 482,; by the homology alignment algorithm of Needleman and Wunsch (1970) J. Mol. Biol., 48: 443 ; by the search for similarity method of Pearson and Lipman (1988) Proc. Natl. Acad. Sci. USA, 8: 2444; by computerized implementations of these algorithms, including, but not limited to: CLUSTAL in the PC/Gene program by Intelligenetics, Mountain View, Calif., GAP, BESTFIT, BLAST, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group (GCG), 7 Science Dr., Madison, Wisc., USA; the CLUSTAL program is well described by Higgins and Sharp (1988) Gene 73: 237-244; Corpet et al. (1988) Nucleic Acids Research, 16:881-90; Huang, et al., Computer Applications in the Biosciences, 8:1-6, 1992; and Pearson, et al. (1994) Methods in Molecular Biology, 24:7-331. The BLAST family of programs which can be used for database similarity searches includes: BLASTN for nucleotide query sequences against nucleotide database sequences; BLASTX for nucleotide query sequences against protein database sequences; BLASTP for protein query sequences against protein database sequences; TBLASTN for protein query sequences against nucleotide database sequences; and TBLASTX for nucleotide query sequences against nucleotide database sequences. See, Current Protocols in Molecular Biology, Chapter 19, Ausubel, et al., Eds., Greene Publishing and Wiley-Interscience, New York, 1995. New versions of the above programs or new programs altogether will undoubtedly become available in the future, and can be used with the present invention.
- Unless otherwise stated, sequence identity/similarity values provided herein refer to the value obtained using the BLAST 2.0 suite of programs, or their successors, using default parameters. Altschul et al. (1997) Nucleic Acids Res, 2:3389-3402. It is to be understood that default settings of these parameters can be readily changed as needed in the future.
- As those ordinary skilled in the art will understand, BLAST searches assume that proteins can be modeled as random sequences. However, many real proteins comprise regions of nonrandom sequences which may be homopolymeric tracts, short-period repeats, or regions enriched in one or more amino acids. Such low-complexity regions may be aligned between unrelated proteins even though other regions of the protein are entirely dissimilar. A number of low-complexity filter programs can be employed to reduce such low-complexity alignments. For example, the SEG (Wooten and Federhen, (1993) Comput. Chem. 17:149-163) and XNU (Claverie and States (1993) Comput. Chem., 17:191-1) low-complexity filters can be employed alone or in combination.
- "Sequence identity" or "identity" in the context of two nucleic acid or polypeptide sequences includes reference to the residues in the two sequences which are the same when aligned for maximum correspondence over a specified comparison window, and can take into consideration additions, deletions and substitutions. When percentage of sequence identity is used in reference to proteins it is recognized that residue positions which are not identical often differ by conservative amino acid substitutions, where amino acid residues are substituted for other amino acid residues with similar chemical properties (for example, charge or hydrophobicity) and therefore do not deleteriously change the functional properties of the molecule. Where sequences differ in conservative substitutions, the percent sequence identity may be adjusted upwards to correct for the conservative nature of the substitution. Sequences which differ by such conservative substitutions are said to have sequence similarity. Approaches for making this adjustment are well-known to those of skill in the art. Typically this involves scoring a conservative substitution as a partial rather than a full mismatch, thereby increasing the percentage sequence identity. Thus, for example, where an identical amino acid is given a score of 1 and a non-conservative substitution is given a score of zero, a conservative substitution is given a score between zero and 1. The scoring of conservative substitutions is calculated, for example, according to the algorithm of Meyers and Miller (1988) Computer Applic. Biol. Sci., 4: 11-17 for example, as implemented in the program PC/GENE (Intelligenetics, Mountain View, Calif., USA).
- "Percentage of sequence identity" means the value determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotide sequence in the comparison window may comprise additions, substitutions, or deletions (i.e., gaps) as compared to the reference sequence (which does not comprise additions, substitutions, or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity.
- The term "substantial identity" or "homologous" in their various grammatical forms in the context of polynucleotides means that a polynucleotide comprises a sequence that has a desired identity, for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%, compared to a reference sequence using one of the alignment programs described using standard parameters. One of skill will recognize that these values can be appropriately adjusted to determine corresponding identity of proteins encoded by two nucleotide sequences by taking into account codon degeneracy, amino acid similarity, reading frame positioning and the like. Substantial identity of amino acid sequences for these purposes n normally means sequence identity of at least 60%, more preferably at least 70%, 80%, 90%, and even more preferably at least 95%.
- Another indication that nucleotide sequences are substantially identical is if two molecules hybridize to each other under stringent conditions. However, nucleic acids which do not hybridize to each other under stringent conditions are still substantially identical if the polypeptides which they encode are substantially identical. This may occur, for example, when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. One indication that two nucleic acid sequences are substantially identical is that the polypeptide which the first nucleic acid encodes is immunologically cross reactive with the polypeptide encoded by the second nucleic acid, although such cross-reactivity is not required for two polypeptides to be deemed substantially identical.
- The term "substantial identity" or "homologous" in their various grammatical forms in the context of peptides indicates that a peptide comprises a sequence that has a desired identity, for example, at least 60% identity, preferably at least 70% sequence identity to a reference sequence, more preferably 80%, still more preferably 85%, even more preferably at least 90% or 95% sequence identity to the reference sequence over a specified comparison window. Preferably, optimal alignment is conducted using the homology alignment algorithm of Needleman and Wunsch (1970) J. Mol. Biol., 48:443. An indication that two peptide sequences are substantially identical is that one peptide is immunologically reactive with antibodies raised against the second peptide, although such cross-reactivity is not required for two polypeptides to be deemed substantially identical. Thus, a peptide is substantially identical to a second peptide, for example, where the two peptides differ only by a conservative substitution. Peptides which are "substantially similar" share sequences as noted above except that residue positions which are not identical may differ by conservative amino acid changes. Conservative substitutions typically include, but are not limited to, substitutions within the following groups: glycine and alanine; valine, isoleucine, and leucine; aspartic acid and glutamic acid; asparagine and glutamine; serine and threonine; lysine and arginine; and phenylalanine and tyrosine, and others as known to the skilled person.
- "Biological subject" as used herein refers to a target biological object obtained, reached, or collected in vivo, ex-vivo, or in situ, that contains or is suspected of containing nucleic acids or polypeptides corresponding to a biomarker of Table 1.
- "Biological sample" as used herein refers to a sample obtained from a biological subject, including sample of biological tissue or fluid origin, obtained, reached, or collected in vivo, ex-vivo, or in situ, that contains or is suspected of containing nucleic acids or polypeptides corresponding to a biomarker of Table 1. A biological sample also includes samples from a region of a biological subject containing precancerous or cancer cells or tissues. Such samples can be, but are not limited to, organs, tissues, fractions and cells isolated from mammals including, humans such as a patient. Biological samples also may include sections of the biological sample including tissues, for example, frozen sections taken for histologic purposes. A biological sample, as described herein, can be: a "control" or a "control sample" or a "test sample". A biological sample can be obtained from the uterus using commonly employed clinical practices (e.g., aspiration, brush, curettage, or hysteroscopy).
- A "control" or "control value" refers to a representative of healthy, endometrial cancer-free biological subject or information obtained from a different individual or a normalized value, which can be based on baseline data obtained from a population or other acceptable sources. A control also can refer to a given level of a biomarker of Table 1, representative of the endometrial cancer-free population, that has been previously established based on measurements from normal, endometrial cancer-free individuals. A control also can be a reference data point in a database based on data obtained from control samples representative of a cancer-free population. Further, a control can be established by a specific age, sex, ethnicity or other demographic parameters. In some contexts, the control is implicit in the particular measurement. A control value or control can also refer to a "control score". Control scores can be values obtained from the determination of the expression level of one or more biomarkers of the invention. For example, different programs and algorithms are commercially available for generating formulas that yield a score value based on the measurement of the levels of one or more biomarkers, that can indicate whether an individual is likely to have a condition or not. In another example, a score over or below a certain threshold that may indicate an increased (or decreased) likelihood of having the disease. A control score value can be based on a single marker or a combination of markers.
- A "control sample" refers to a sample of biological material representative of healthy, cancer-free animals or a normal biological subject obtained from a cancer-free population. The level of a biomarker of Table 1, in a control sample is desirably typical of the general population of normal, cancer-free animals of the same species. This sample either can be collected from an animal for the purpose of being used in the methods described in the present invention or it can be any biological material representative of normal, cancer-free animals suitable for use in the methods of this invention. A control sample also can be obtained from normal tissue from the animal that has cancer or is suspected of having cancer.
- A "test sample" as used herein refers to a biological sample, including sample of biological tissue or fluid origin, obtained, reached, or collected in vivo, ex-vivo, or in situ, that contains or is suspected of containing nucleic acids or polypeptides corresponding to a biomarker of Table 1. A test sample also includes biological samples containing precancerous or cancer cells or tissues. A test sample also may include sections of the biological sample including tissues, for example, frozen sections taken for histologic purposes.
- "Providing a biological subject, a biological sample, or a test sample" means to obtain a biological subject in vivo, ex-vivo, or in situ, including tissue or cell sample for use in the methods described in the present invention. Most often, this will be done by removing a sample of cells from an animal, but also can be accomplished in vivo, ex-vivo, or in situ, or by using previously isolated cells (for example, isolated from another person, at another time, and/or for another purpose). The sample can also be obtained from sources such as blood, serum, and uterine fluid.
- "Data" includes, but is not limited to, information obtained that relates to "biological sample", "test sample", "control sample", and/or "control", as described above, wherein the information is applied in generating a test level for diagnostics, prevention, monitoring or therapeutic use. The present invention relates to methods for comparing and compiling data wherein the data is stored in electronic or paper formats. Electronic format can be selected from the group consisting of electronic mail, disk, compact disk (CD), digital versatile disk (DVD), memory card, memory chip, ROM or RAM, magnetic optical disk; tape, video, video clip, microfilm, internet, shared network, shared server and the like; wherein data is displayed, transmitted or analyzed via electronic transmission, video display, telecommunication, or by using any of the above stored formats; wherein data is compared and compiled at the site of sampling specimens or at a location where the data is transported following a process as: described above.
- "Overexpression" of a gene or an "increased," or "elevated," level of a ribonucleotide or protein refers to a level of the gene, ribonucleotide or polypeptide that, in comparison with a control level/value of gene, ribonucleotides or polypeptide, is detectably higher. Comparison may be carried out by statistical analyses on numeric measurements of the expression; or, it may be done through visual examination of experimental results by qualified researchers. Examples of overexpression include a change of 10% or more, 20% or more 30% or more, 40% or more, or 50% or more in affected as compared to non-affected.
- "Underexpression" of a gene or a "decreased," or "lower," level of a ribonucleotide or protein refers to a level of the gene, ribonucleotide or polypeptide that, in comparison with a control level of gene, ribonucleotides or polypeptide, is detectably lower. Comparison may be carried out by statistical analyses on numeric measurements of the expression; or, it may be done through visual examination of experimental results by qualified researchers. Examples of underexpression include a change of 10% or more, 20% or more 30% or more, 40% or more, or 50% or more in affected as compared to non-affected.
- A level of ribonucleotide or polypeptide, that is "expected" in a control sample refers to a level that represents a typical, cancer-free sample, and from which an elevated, or diagnostic, presence of the polypeptide or polynucleotide, can be distinguished. Preferably, an "expected" level will be controlled for such factors as the age, sex, medical history, etc. of the mammal, as well as for the particular biological subject being tested.
- The terms "isolated," "purified," or "biologically pure" refer to material that is free to varying degrees from components which normally accompany it as found in its native state. "Isolate" denotes a degree of separation from original source or surroundings. "Purify" denotes a degree of separation that is higher than isolation. A "purified" or "biologically pure" protein is sufficiently free of other materials such that any impurities do not materially affect the biological properties of the protein or cause other adverse consequences. That is, a nucleic acid or peptide of this invention is purified if it is substantially free of cellular material, viral material, or culture medium when produced by recombinant DNA techniques, or chemical precursors or other chemicals when chemically synthesized. Purity and homogeneity are typically determined using analytical chemistry techniques, for example, polyacrylamide gel electrophoresis or high performance liquid chromatography. The term "purified" can denote that a nucleic acid or protein gives rise to essentially one band in an electrophoretic gel. For a protein that can be subjected to modifications, for example, phosphorylation or glycosylation, different modifications may give rise to different isolated proteins, which can be separately purified. Various levels of purity may be applied as needed according to this invention in the different methodologies set forth herein; the customary purity standards known in the art may be used if no standard is otherwise specified.
- An "isolated nucleic acid molecule" can refer to a nucleic acid molecule, depending upon the circumstance, that is separated from the 5' and 3' coding sequences of genes or gene fragments contiguous in the naturally occurring genome of an organism. The term "isolated nucleic acid molecule" also includes nucleic acid molecules which are not naturally occurring, for example, nucleic acid molecules created-by recombinant DNA techniques.
- "Nucleic acid" refers to deoxyribonucleotides or ribonucleotides and polymers thereof in either single- or double-stranded form. The term encompasses nucleic acids containing known nucleotide analogs or modified backbone residues or linkages, which are synthetic, naturally occurring, and non-naturally occurring, which have similar binding properties as the reference nucleic acid, and which are metabolized in a manner similar to the reference nucleotides. Examples of such analogs include, without limitation, phosphorothioates, phosphoramidates, methyl phosphonates, chiral methyl phosphonates, 2-O-methyl ribonucleotides, and peptide-nucleic acids (PNAs).
- Unless otherwise indicated, a particular nucleic acid sequence also implicitly encompasses conservatively, modified variants thereof (for example, degenerate codon substitutions) and complementary sequences, as well as the sequence explicitly indicated. Specifically, degenerate codon substitutions may be achieved by generating sequences in which the third position of one or more selected (or all) codons is substituted with suitable mixed base and/or deoxyinosine residues (Batzer et al. (1991) Nucleic Acid Res, 19:081; Ohtsuka et al. (1985) J. Biol. Chem., 260:2600-2608; Rossolini et al. (1994) Mol. Cell Probes, 8:91-98). The term nucleic acid can be used interchangeably with gene, cDNA, mRNA, oligonucleotide, and polynucleotide.
- A "label" or a "detectable moiety" is a composition that when linked with the nucleic acid or protein molecule of interest renders the latter detectable, via spectroscopic, photochemical, biochemical, immunochemical, or chemical means. For example, useful labels include radioactive isotopes, magnetic beads, metallic beads, colloidal particles, fluorescent dyes, electron-dense reagents, enzymes (for example, as commonly used in an ELISA), biotin, digoxigenin, or haptens. A "labeled nucleic acid or oligonucleotide probe" is one that is bound, either covalently, through a linker or a chemical bond, or noncovalently, through ionic bonds, van der Waals forces, electrostatic attractions, hydrophobic interactions, or hydrogen bonds, to a label such that the presence of the nucleic acid or probe may be detected by detecting the presence of the label bound to the nucleic acid or probe.
- As used herein a "nucleic acid or oligonucleotide probe" is defined as a nucleic acid capable of binding to a target nucleic acid of complementary sequence through one or more types of chemical bonds, usually through complementary base pairing, usually through hydrogen bond formation. As used herein, a probe may include natural (i.e., A, G, C, or T) or modified bases (7-deazaguanosine, inosine, etc.). In addition, the bases in a probe may be joined by a linkage other than a phosphodiester bond, so long as it does not unduly interfere with hybridization. It will be understood by one of skill in the art that probes may bind target sequences lacking complete complementarity with the probe sequence depending upon the stringency of the hybridization conditions. The probes are preferably directly labeled with isotopes, for example, chromophores, lumiphores, chromogens, or indirectly labeled with biotin to which a streptavidin complex may later bind. By assaying for the presence or absence of the probe, one can detect the presence or absence of a target gene of interest.
- The phrase "selectively (or specifically) hybridizes to" refers to the binding, duplexing, or hybridizing of a molecule only to a particular nucleotide sequence under stringent hybridization conditions when that sequence is present in a complex mixture (for example, total cellular or library DNA or RNA).
- The phrase "stringent hybridization conditions" refers to conditions under which a probe will hybridize to its target complementary sequence, typically in a complex mixture of nucleic acids, but to no other sequences. Stringent conditions are sequence-dependent and circumstance-dependent; for example, longer sequences can hybridize with specificity at higher temperatures. An extensive guide to the hybridization of nucleic acids is found in Tijssen (1993) Techniques in Biochemistry and Molecular Biology-Hybridization with Nucleic Probes, "Overview of principles of hybridization and the strategy of nucleic acid assays". In the context of the present invention, as used herein, the term "hybridizes under stringent conditions" is intended to describe conditions for hybridization and washing under which nucleotide sequences at least 60% homologous to each other typically remain hybridized to each other. Preferably, the conditions are such that sequences at least about 65%, more preferably at least about 70%, and even more preferably at least about 75% or more homologous to each other typically remain hybridized to each other.
- Generally, stringent conditions are selected to be about 5 to 10 C lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength pH. The Tm is the temperature (under defined ionic strength, pH, and nucleic concentration) at which 50% of the probes complementary to the target hybridize to the target sequence at equilibrium (as the target sequences are present in excess, at Tm, 50% of the probes are occupied at equilibrium). Stringent conditions will be those in which the salt concentration is less than about 1.0 M sodium ion, typically about 0.01 to 1.0 M sodium ion concentration (or other salts) at pH 7.0 to 8.3 and the temperature is at least about 30 C for short probes (for example, 10 to 50 nucleotides) and at least about 60 C for long probes (for example, greater than 50 nucleotides). Stringent conditions also may be achieved with the addition of destabilizing agents, for example, formamide. For selective or specific hybridization, a positive signal is at least two times background, preferably 10 times background hybridization.
- Exemplary stringent hybridization conditions can be as following, for example: 50% formamide, 5xSSC and 1% SDS, incubating at 42 C, or 5xSSC and 1% SDS, incubating at 65 C., with wash in 0.2xSSC and 0.1% SDS at 65 C. Alternative conditions include, for example, conditions at least as stringent as hybridization at 68 C for 20 hours, followed by washing in 2xSSC, 0.1% SDS, twice for 30 minutes at 55 C and three times for 15 minutes at 60 C. Another alternative set of conditions is hybridization in 6xSSC at about 45 C, followed by one or more washes in 0.2xSSC, 0.1% SDS at 50-65 C. For PCR, a temperature of about 36 C is typical for low stringency amplification, although annealing temperatures may vary between about 32 C and 48 C depending on primer length. For high stringency PCR amplification, a temperature of about 62 C is typical, although high stringency annealing temperatures can range from about 50 C to about 65 C, depending on the primer length and specificity. Typical cycle conditions for both high and low stringency amplifications include a denaturation phase of 90 C to 95 C for 30 sec. to 2 min., an annealing phase lasting 30 sec. to 2 min., and an extension phase of about 72 C for 1 to 2 min.
- Nucleic acids that do not hybridize to each other under stringent conditions can still be substantially identical if the polypeptides which they encode are substantially identical. This occurs, for example, when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. In such cases, the nucleic acids typically hybridize under moderately stringent hybridization conditions. Exemplary "moderately stringent hybridization conditions" include a hybridization in a buffer of 40% formamide, 1 M NaCl, 1% SDS at 37 C, and a wash in 1xSSC at 45 C. A positive hybridization is at least twice background. Those of ordinary skill will readily recognize that alternative hybridization and wash conditions can be utilized to provide conditions of similar stringency.
- The term "target gene" or "target biomarker" or "target nucleic acid" or "target protein" can refer to a target nucleic acid (DNA and RNA) or protein (or polypeptide), (e.g., corresponding to the biomarkers in Table 1) and can include their polymorphic variants, alleles, mutants, and interspecies homologs that have (i) substantial nucleotide sequence homology (for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%) with the nucleotides sequence indicated in Ensembl database for the indicated ID number; or (ii) at least 65% sequence homology with the amino acid sequence as indicated in the Ensembl record; or (iii) substantial nucleotide sequence homology (for example, at least 60% identity, preferably at least 70% sequence identity, more preferably at least 80%, still more preferably at least 90% and even more preferably at least 95%) with the nucleotide sequence as set forth in the Ensembl record with substantial sequence homology with the encoded amino acid sequence. As used in herein, and unless otherwise specified, these terms refer the entire gene sequence, mRNA sequence, and/or protein sequence as well as fragments of these sequences. In a more specific definition, these terms refer to the minimal amount of nucleic acid or amino acid sequence that can be used to identify biomarker in a specific manner. The skilled artisan recognizes that the target genes/biomarker can have numerous splice forms and variants. When referring to a specific target gene or locus by a reference number (e.g., Entrez gene ID or Ensembl), all splices forms and variant which are included in the various embodiments of the invention. The target gene/biomarker can also comprise a regulatory element. These sequences are representative of one particular individual in the population of humans. Humans vary from one to another in their gene sequences. These variations are very minimal, sometimes occurring at a frequency of about 1 to 10 nucleotides per gene. Different forms of any particular gene exist within the human population. These different forms are called allelic variants. Allelic variants often do not change the amino acid sequence of the encoded protein; such variants are termed synonymous. Even if they do change the encoded amino acid (non-synonymous), the function of the protein is not typically affected. Such changes are evolutionarily or functionally neutral. When a gene ID (e.g., genbank or Ensembl) is referred to in the present application all allelic variants are intended to be encompassed by the term. The gene ID sequences given for a biomarker are provided merely as representative examples of a wild-type human sequence. The invention is not limited to a single allelic form of the amplified genes or regions (and proteins they encode).
- The following examples are included to demonstrate preferred embodiments of the invention. It should be appreciated by those of skill in the art that the techniques disclosed in the examples which follow represent techniques used by the inventor to function well in the practice of the invention, and thus can be considered to constitute preferred modes for its practice. However, those of skill in the art should, in light of the present disclosure, appreciate that many changes can be made in the specific embodiments which are disclosed and still obtain a like or similar result.
- In order to identify biomarkers for predicting and/or diagnosing endometrial cancer, gene expression levels from fifty-six Endometrial primary tumors in several differentiation stages were compared with 10 normal (i.e., not having endometrial cancer) endometrial tissues by DNA microarray technique. This technique allows us to check the expression of the whole genome in a particular type of cell, tissue, organ, or in this case, check the differential gene expression between endometrial cancer and healthy endometrial tissue. A microarray chip contains small DNA sequences arranged in a regular pattern with specific addresses for probes for typically thousands of genes.
- The amount of specific mRNAs in a sample can be estimated by it hybridization signal on the array.
- Tumor samples were obtained from patients who underwent surgery and control tissue was obtained from non affected regions of endometrial tissue from the same patients. During preparation of the specimens, care was taken to macroscopically dissect the cancer away from any adjacent myometrium.
- Ten control samples (nine of them were paired with their corresponding tumor samples and the tenth was an atrophic endometrium) were used and the basic characteristics of the other test samples are summarized in Table 3 below.

Quantity and quality of the obtained RNA was measured with a Nanodrop (Nandrop ND-1000, Agilent 2100 Bioanalyzer) and low quality RNA was discarded from the array hybridization process.
- Microarrays for Gene Expression were designed by the Tethys algorithm using the ENSEMBL database. For sequences where we did not find high quality probes, we complemented the design with Oryzon Optimized Agilent probes. DNA microarray synthesis was outsourced to Agilent.
- The Whole Genome Gene Expression Array contains:
- 20148 Oryzon High Quality probes from ENSEMBL Database.
- 5698 Oryzon Tm optimized Agilent probes.
- Cy3 and Cy5 labeled aRNA was produced using the MessageAmplification kit by Ambion (Ref: 1819 for 96x kit or Ref: 1751 for 20x kit). These kits are used with some modifications introduced by Oryzon genomics. RNA labeling was performed essentially using the Eberwine protocol (Van Gelder, 1992) commercialized by Ambion with the MessageAmplification Kit (Ambion/Applied Biosystems) with minor modifications. 500 ng of total RNA was reverse transcribed in presence of oligo(dT)24 , second-strand synthesis was generated and transcription of this dsDNA was prepared using CTP_Cy3 or CTP_Cy5 (PerkinElmer). Amplified cRNA was quantified by Nanodrop ND-1000 and cRNA quality was controlled with the Agilent RNA Bionalyzer 2100.
- Microarray hybridization was performed at 60°C and 17 hours hybridization time according to Agilent indications, using Agilent gaskets (G2534-60002), Agilent hybridization chambers (G2534A) and in an Agilent DNA Hybridization Oven (G2545A). Oryzon hybridization controls are also used in hybridization process. Controls for the hybridization process corresponding to 3 cDNA clones of maize (Xet, Zm42,Exp) were included in all analysis. Exp is used as the negative spike control and was not amplified nor labeled. For Xet and Zm42 PCR fragments were generated by PCR amplification from the vector with universal primers and cRNA was generated using in vitro transcription systems (T7 or T3 Megascript kit; Ambion) with CTP_Cy3 or CTP_Cy5 (PerkinElmer). Both of the positive spike controls Xet and Zm42 were with both the Cy5 and Cy3 fluorofor.
- Initial Raw Data were obtained using an Agilent DNA Microarray Scanner (G2505B) and Agilent acquisition software (Feature Extraction Software). The extraction protocol performed does not use background subtraction, computation of dye biases and ratio correction.
- A large number of controls were included in the microarray designs to monitor scanner and array performance and to control spatial homogeneity and correct deviations. This wary, the overall error on the microrarray data measurements can be estimated by the spreading analysis of the data from the controls.
- The mean fold change or M values can be ranked based on their probability of being different from 0, according to the absolute value of the regularized t-statistic (Baldi and Long, 2001) which uses a Bayesian framework to derive a modified and improved t-student statistics. To make Fold Change based selection, the mean M distribution was used. This distribution is adjusted to a normal distribution and an iterative process is used to define the mean M numbers that are outside the distribution. The cut-off is chosen as n times the Standard deviations (σ) from the mean. This method generates a robust mean and standard deviation and allows to dynamically adjusting the cut-off value to the noise distribution of the data. Typically, values with mean FC>3σ or mean FC<-3σ of the sample data distribution were selected.
- An indirect analysis comparison where the expression levels of particular biomarkers in tumor samples were compared to a reference RNA pool obtained from a group of over 20 cell lines (melanoma, lung cancer, ovarian cancer, colon cancer, and several non-cancer cell lines). The expression level of particular genes in the normal samples (controls) were compared to the same reference pool and final expression fold changes between tumor and normal endometrial tissue were generated in silico eliminating the reference pool.
- Candidate genes were selected as biomarkers for endometrial cancer based on fold overexpression, p-value, and other factors. Table 1 in the Detailed Description of the Invention shows 17 overexpressed genes and 3 genes underexpresssed identified using these procedures. The overexpression of these genes was validated by RT-PCR as described in the next examples.
- The results from the microarray studies are summarized in Table 1 in the Detailed Description of the Invention, which shows the common abbreviation used for the gene, the ENSMBL gene, transcript and protein accession numbers along with the fold overexpression and calculated p-values.
- Endometrial aspirates were collected with the help of a Cornier pipelle, after complete informed consent was obtained from all patients. The aspirate (uterine fluid) was immediately transferred to an eppendorf tube containing 500 microliters of a RNA preserving solution (RNA later, Ambion). The sample was centrifuged and the pellet containing a representative population of cells from the uterine cavity was further processed for RNA extraction (Qiagen). Quality tests (Bioanalyzer) were performed before the analysis of gene expression by Taqman technology for the selected markers of endometrial carcinoma.
- The levels of biomarkers from primary tumor sample and uterine fluid sample obtained by the procedure of Example 2 were compared as by RT-PCR following the general RT-PCR protocol as described in Example 4. The biomarkers in this study included ACAA1, AP1M2, CGN, DDR1, EPS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNA183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN whose expression level was found to be surprisingly correlated between the primary tumor and endometrial aspirates (uterine fluid).

Figure 1 . As can be seen inFigure 1 , the expression level of a number of biomarkers of endometrial cancer are correlated in uterine fluid and primary tumor. In particular, it was found that there was a high level of correlation of expression of biomarkers corresponding to ACAA1, AP1M2, CGN, DDR1, EPS8L2, PASTED1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPPIR16A, RASSF7, RNF183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN in tumor sample and in samples obtained from uterine fluid. Thus, the inventors have surprisingly finding of a group of genes that can be used to diagnosis or predict an increased likelihood of endometrial cancer based on their expression levels in samples obtained from uterine fluid. Furthermore, the inventors have shown that uterine fluid can be used to assess biomarkers for endometrial cancer. For example, prognostic biomarkers for endometrial cancer, biomarkers for staging endometrial cancer, biomarkers for determining the type of endometrial cancer (e.g., Type 1 vs. Type II) or type (endometrioid, clear cell, serrous, etc.), auxiliary diagnostic biomarkers, differential diagnosis biomarkers, can be assayed in uterine fluid to characterize the cancer. - Once array data were obtained, a group of upregulated and downregulated genes in tumor samples compared with normal tissue were selected in-part based on their p-values and standard deviations. These candidates were selected to determine their expression levels by an independent technique using a different set of tumor samples.
- Microfluidic Cards (MFC) from Applied Biosystems were used to perform RT-PCR with RNA isolated from tumor and normal Endometrial tissue samples. In this case both types of tissues, healthy and carcinogenic were obtained from the same patient by microdissection procedures. These studies confirmed the microarray results for most of the markers of Table 1. Another set of RT-PCT studies were performed using aspirates obtained from endometrial cancer patients (confirmed) and aspirates from non-affected individuals. These studies using aspirates samples are described in more detail below.
- Aspirate samples were obtained following a procedure similar to that described in Example 2. The description of patient characteristics for the affected and non-affected samples are given in Table 4 and Table 5 below.
- Briefly, wells of the Microfluidic Card contain Applied Biosystems fluorogenic 5' nuclease assays that detect the real-time amplification of the array selected targets. Relative levels of gene expression are determined from the fluorescence data generated during PCR using the ABI PRISM® 7900HT Sequence Detection System (7900HT SDS) Relative Quantification software.
- Data analysis was made using the comparative ΔΔCt method of relative quantification. Differentially expressed genes were confirmed by thorough statistical analysis using a modified T- test.
- The samples used for the study described in this Example included:
- Samples from 30 patients having endometrial cancer: 25 endometroid adenocarcinomas with 9 in G3, 9 in G2 and 7 in G1. And 5 tumor samples from different type II carcinomas (4 in G3 and 1 in G2)
- Samples from 24 patients not having endometrial cancer ("controls" or "normal"). These were a heterogeneous mix of samples some of them from patients with other non-tumoral pathologies liked polyps: 4 samples from patients with atrophic endometriod, 4 normal samples, two from patients having polyps from post-menopausical women and 11 samples from pre-menopausical women (7 of them in secretory phase and 4 in proliferative phase of the cycle). See Tables below for a summary of samples.

Aspirate samples were collected as described in Example 2.
- RT-PCR was performed following Applied Biosystem standard protocol for the 7900HT system. The protocol consisted in a two-step method where the first step is the generation of cDNA from the RNA samples using a High Capacity cDNA Kit and the second step is the amplification of cDNA, once loaded in the MFC, by the ABI PRISM® 7900 HT system.
- RT-PCR data were collected for a set of 20 genes identified in Example 1 and quantified relative to POLR2A levels. The RQ values for the aspirates corresponding to the 30 tumor samples and the 24 samples that were not endometrial cancer (normals) are illustrated in a box and whiskers plot, see
Figure 2A and2B . Table 2 in the Detailed Description of the Invention gives a summary of the mean RQ values, standard error of the mean and p-values calculated for these markers in this sample set. As can be seen, the p-values obtained using the control sample set in the microarray studies (Table 1) were significantly improved in a different sample set using different techniques (microarray versus RT-PCR) and different sources of sample (aspirates versus primary tumor). In most cases the p-value improved over 100-fold for the biomarkers. This is related in part to the robust nature of the microarray experimental design and robust selection of markers based on the Inventors' criteria. - The next table shows the sensitivity and specificity for each individual gene on the patent application and the area under de ROC (AUROC) curve for each gene when comparing the RQ values from the 30 tumour samples and the 24 control samples. A support vector machine (SVM) program was used to calculate the data. As can be seen in the table below, the markers identified in these studies have excellent sensitivity and/or specificity for predicting an increased likelihood and/or diagnosis of endometrial cancer. Furthermore, the AUROC values for these biomarkers indicate that these markers are very useful for diagnosis of endometrial cancer.

At the same time, aspirates from pre-menopausical women could be divided in two categories depending of the uterine endometrial cycle phase they were when the sample was taken: proliferative or secretory. The characterization of secretory versus proliferative phase patients was accomplished by a pathologist using standard techniques.
- Some of the genes tested could give a false positive result for endometrial cancer if the aspirate was taken from pre-menopausical women in secretory phase. In order to check which genes could give false positives depending of the cycle phase or which others could distinguish between tumour samples and secretory phase, we performed a statistical analysis comparing tumours with different control groups.
- tumors versus control samples (all the control samples: 24 samples)
- tumors versus control samples minus the ones in secretory phase: 17 samples
- tumors samples versus control samples in secretory phase: 7 samples
- tumors samples versus control samples from postmenopausical women: 11 samples
- The area ROC for each comparison was calculated using the GraphPad Prism program and anova test was applied to see if the differences among these groups were significant.
- In the Tables below the following abbreviations are used for p-values:
- *** p<0.0001
- ** p<0.001
- *p<0.01
- As it is shown on the tables there are genes, like P4HB or SOCS2, which separate the tumour samples from the control independently of the nature of the control samples (post-menopausical, pre-menopausical in secretory or in proliferative). Other genes like P2RX4 or PPFIBP2, could distinguish between a tumour sample (affected) and a sample in secretory phase better as compared to controls from postmenopausical women.
- This observation opens the possibility of using different algorithms and/or different set of genes depending if the test is interrogating pre-menopausical or post-menopausical women. Furthermore, a primary modality for screening for endometrial problems is the trans-vaginal ultrasound which is used to estimate endometrial thickness where patients having a thicker endometrium (over a certain threshold) are likely to have endometrial cancer or another disease or condition. Endometrium thickness also varies as a function of the phase of the menstrual with individuals in secretory phase having a thicker endometrium as compared to individuals in proliferative phase. Thus, these finding indicate that the methods and biomarkers of the invention can be used to aid and improve the ability of transvaginal ultrasound to identify endometrial cancer.

- In reference to
Figure 2A and2B (box and whisker plot), RQ: relative quantity, it is the relative amount of RNA for a specific gene present on the tumours samples referred to the amount present on the control sample for the same gene. - To calculate the RQ the Ct values of each gene were normalise respect to the Ct of the endogenous gene to get the delta Ct. The formula 2-(deltaCt) was used to calculate de RQ.
- A number of endogenous genes can be used as a control for normalization as well as other controls for normalization. In one example a preferred endogenous gene has the following characteristics: it is a gene constitutively expressed in the same tissue under different circumstances like for example cancer development. So it could be used to normalize differences in the amount of cDNA when loading the samples or variations due to experimental reasons for the qRT-PCR.
- We have tested four different housekeeping genes as possible endogenous genes for normalization purposes: 18S, B2M, PFN-1 and POLR2A. Finally, POLR2A was the most stable gene from all of them and all the calculations and statistics were done using it as endogenous. Its expression level is similar to the genes questioned in our test and different as compared to 18 S whose expression is quiet high compared to the genes selected for the test. It is contemplated that endogenous biomarkers such as POLR2A, B2M, PFN1, HMBS, G6PD, or PABPN1 or another stable gene can be used for normalization purposes in the methods of the inventionif they so require.
- A support vector machine based algorithm was used to identify combinations of markers of Table 1 that are useful for predicting endometrial cancer and/or an increased likelihood of having endometrial cancer. In particular, the publically available program DTREG program was used to analyze the data (see the www at DTREG.COM).
- Support vector machine algorithm can be used for many applications including identifying gene expression profiles for separating populations having different phenotypic characteristics. The idea behind the algorithm is a multidimensional representation of the data, e.g., each marker is plotted on a different dimension and a plane is sought though this multidimensional representation of the data that can separate the phenotypes. The plan through the "middle" is referred to as the separating hyperplane and represents a solution: answers (e.g., expression level over a given threshold value) that fall on one side of the line fall into one category (e.g., cancer) and answers (e.g., expression level over a given threshold value) that follow on the other side of the line correspond to the other category (e.g., no cancer). A number of separating hyper plane can be possible for each dataset. The question becomes which is the best separating hyperplane. In support vector machine theory, the best solution is referred to as the maximum margin hyperplane. This maximum margin hyperplane is the one that separates the two groups and adopts the maximal distance from any one of the given expression profiles.
- Although individual genes show a high sensitivity and specificity, these parameters are even higher when combined several genes. Some examples of the sensitivity , specificity and AUROC genes combined two to two, three to three, four to four, five to five, six to six, seven to seven and all of them together. See the Table below for a summary of the data.

Thus, these results show that combinations of 2 or more markers chosen from ACAA1, AP1M2, CGN, DDR1, EPS8L2, FASTKD1, GMIP, IKBKE, P2RX4, P4HB, PHKG2, PPFIBP2, PPP1R16A, RASSF7, RNF183, SIRT6, TJP3, EFEMP2, SOCS2, and DCN give unexpectedly good sensitivity and specificity for predicting an increased likelihood and/or diagnosing endometrial cancer. These results were obtained from samples from uterine fluid and indicate that combinations of biomarkers detected in uterine fluid can be useful for diagnosing and/or characterizing endometrial cancer. Furthermore, these results were obtained in samples from pre and post menopausal women and therefore represents a set of markers that can be examined across these types of patients. It is noted that different programs and algorithms can be used to generate profiles or fingerprint patterns. The invention is intended to encompass profiles and/or fingerprint patterns using programs and algorithms other than DTREG as used herein. The profiles identified in Table 11 are non-limiting examples used to illustrate that combinations of the biomarkers of Table 1 have excellent sensitivity and specificity for endometrial cancer.
- The values of sensitivity and specificity although fully define the validity of a diagnostic test have the disadvantage of not providing relevant information when making a clinical decision to a particular test result. However, they have the advantage of been intrinsic properties to the test and define its validity irrespective of the prevalence of the disease in the population to which it applies.
- It is the probability of classifying correctly an individual patient or the probability that a individual with cancer obtains a positive result when applying the diagnostic test
- It is the probability of classifying correctly a healthy individual or the probability that a healthy individual obtaining a negative result when applying the diagnostic test Sensitivity and specificity can, therefore, to assess the validity of a diagnostic test. However, these concepts are not much help in clinical practice. When a patient undergoes a diagnostic test, the doctor has no a priori information about their diagnosis so the question arises to the next one: given a positive (or negative) on the test? What is the probability that the individual tested has the disease (or not)? These probabilities are known as positive predictive value and negative predictive value of a particular test. Positive predictive value is the probability of having the disease if the individual has a positive result when applying the diagnostic test. Negative predictive value is the probability that an individual who has obtained a negative result on the test, is actually healthy.
- Clinicians prefer diagnostic tests with high negative predictive value as they can not allow people with cancer get a wrong diagnosis. For this reason we have prioritized these combinations which give us the highest negative predictive values.
- The follow values in Table 12 were calculated using the indicated markers as determined by RT-PCR in uterine fluid samples.

FIG. 17 , the first combination is able to classify all the samples correctly but the percentage of some healthy samples of having cancer are very close to 50%: some cancer samples are too close to be misclassified when using this combination. In summary, the risk of misclassifying cancer patients with a false diagnosis. Although the combinations inFIG. 18 and FIG. 19 misclassify one and two healthy patients samples respectively, both of them classify correctly all the cancer patients and they do it with a higher percentage of risk of cancer than the previous combination. For that reason these combinations are valuable from a clinical point of view. Example 6: Detection of Protein Corresponding to the - Detection of protein corresponding to the Biomarkers of Table 1 can be accomplished by any number of means available to the skill artisan. According to this method samples from controls (or a control value is established) and affected individuals are obtained (e.g., serum, tissue, and uterine fluid) and probe for with antibodies selective or specific to the particular biomarker. One method for detecting the proteins is by western blot analysis and is exemplified as in the case of P4HB.
- Western blot analysis from human samples from normal endometrial yissue and tumour endometrial cancer tissues in order to test the protein level of P4HB (aprox. 60 kDa) in these samples.
- Gels were loaded with 40 ug of total protein extracts from each sample. As can be seen in
Figure 10 , tumor samples stained much more strongly for P4HB as compared to normal tissue. - The samples tested include four normal tissues (N) and four tumour tissues (T). Normal and tumours tissues were obtained from the same patient. As a positive control: total protein extract from the endometrial tumour cell line Isikawa. The Antibody used: LS-C38385 from LifeSpan.
- The results confirm to protein level the results obtained in the array and the TaqMan experiments.
- Western blot analysis was performed for AP1M2, IKBKE, EPS8L2, DDR1, CGN, and TJP3. See FIG.X through FIG.X. These results confirm at the protein level the results obtained in the array and the TaqMan experiments for these biomarkers.
- For immunohistochemistry validation, tissue microarrays were constructed. In order to cover the complete range from normal tissue to different types and grades of endometrial carcinomas, representative areas from 70 paraffin-embedded carcinomas (56 endometrioid, 6 serous papillary, 1 mucinous, 4 clear cell carcinomas, 3 carcinosarcomas), and 11 non-neoplastic endometria (4 atrophic, 3 proliferative, 1 secretory endometrial and 3 hyperplasias), were carefully selected and marked on individual paraffin blocks. Two tissue cores of 1mm in diameter were obtained from each paraffin block and were precisely arrayed in a new paraffin block. Sections of 5µm were obtained from all tissue microarray paraffin blocks. The protocol was approved by the Institutional Review Board at Hospital Vall D'Hebron, and informed consent was obtained from all of the patients. P4HB, PPP1R16A and EPS8L2 were detected by the indirect immunoperoxidase assay with citrate buffer pH 7,3 for antigen retrieval. Sections were incubated with a primary antibodies against P4HB (LS-C38385) and PPP1R16A (H00084988-M06) for 1 h at room temperature using a dilution 1:500 and 1:100, respectively, and EPS8L2 (H00064787-B01) overnight at 1:100 dilution. Thereafter sections were incubated with peroxidase conjugated goat anti-mouse immunoglobulin (EnVision Dual System, DAKO, Glostrup, Denmark). Endogenous peroxidase activity was quenched with 3% H2O2. Sections were washed, and reactions were developed with diaminobenzidine, followed by counterstaining with haematoxylin. Semiquantitative evaluation of the proteins was performed by three independent investigators, scoring the intensity of the stained and the percentage of positive cells.
- TMA immunohistochemistry confirmed the differential expression of the three proteins at the tumoral glands when compared to the normal endometrial glands. P4HB, PPP1R16A and EPS8L2 presented a specific cytoplasmatic expression within the tumoral cells in all carcinoma histological types and grades, and an absence or faint cytoplasmatic stain within the normal epithelial glands. These results confirm at the protein level the results obtained for these proteins in the microarray and quantitative PCR experiments described herein.Example 7: ACAA1
- ACAA1 was found to be overexpressed in endometrial cancer primary tissue as compared to normal endometrial tissue by the microarray experiment described in Example 1. Further studies using RT-PCR demonstrated that ACAA1 was overexpressed in primary endometrial cancer tissue as compared to normal endometrial tissue and it was surprisingly found that ACAA1 was overexpressed in samples obtained from uterine fluid (e.g., aspirates) from patients having endometrial cancer by the methods described in Examples 2-4. Example 5 shows that ACAA1 can be combined with other biomarkers to give excellent predictive power for diagnosis of endometrial cancer.

- AP1M2 (adaptor-related protein complex 1, mu 2 subunit) also known as D9Ertd818e, HSMU1B, MU-1B, MU1B) was found to be overexpressed in endometrial cancer primary tissue as compared to normal endometrial tissue by the microarray experiment described in Example 1. Further studies using RT-PCR demonstrated that AP1M2 was overexpressed in primary endometrial cancer tissue as compared to normal endometrial tissue and it was surprisingly found that AP1M2 was overexpressed in samples obtained from uterine fluid (e.g., aspirates) from patients having endometrial cancer by the method described in Examples 2-4. Example 5 shows that AP1M2 can be combined with other biomarkers to give excellent predictive power for diagnosis of endometrial cancer.
- AP1M2 is a subunit of the heterotetrameric clathrin adaptor-related protein complex 1 (AP-1), that play pivotal roles in many vesicle trafficking pathways within the cell. This protein is capable of interacting with tyrosine-based sorting signals. AP1 is expressed exclusively in epithelial cells. All AP complexes comprise two large subunits of 100-130 kDa (α and β1 in AP1), a medium subunit of 50 kDa (µl in AP1), and a small subunit of 17-20 kDa (σ1 in AP1). PMID: 10338135
- In clathrin-coated vesicles, AP-2 is located between the lipid bilayer and clathrin lattice, and presumably is anchoring clathrin to membrane. AP1M2 is member of the adaptor medium chain family termed Mu1B, which is specifically expressed in polarized epithelial cells and some exocrine cells. Mu1B is most closely related to the ubiquitously-expressed MulA subunit of AP-1 (79% identity at the amino acid level).

Example 5 shows that EPS8L2 can be combined with other biomarkers to give excellent predictive power for diagnosis of endometrial cancer. - The EPS8L2 gene encodes a protein that is related to epidermal growth factor receptor pathway substrate 8 (EPS8), a substrate for the epidermal growth factor receptor. The eps8Ls define a novel family of proteins responsible for functional redundancy in the RTK-activated signaling pathway leading to actin remodeling. Members of this family link growth factor stimulation to actin organization. Members of the eps8 family share a modular organization consisting of a putative PTB domain, a central SH3 domain and a C-terminal effector region. The SH3 domains of eps8Ls display unique binding preferences for peptides containing a proline-X-X-aspartate-tyrosine (pXXDY) consensus and constitute a phylogenetically distinct subfamily within the SH3 domain family. (PMID: 14565974).
- Although EPS8L2 function is unknown, gene expression analyses of breast and thyroid cancers identified Eps8, another member of the family, as a novel putative oncogene and also it was implicated in tumor cell migration in fibrosarcoma cells. (PMID: 16618726) (PMID: 17075124) (PMID: 15289329)

- IKBKE is a member of the large IkB kinase complex capable of phosphorylating IkB. IKK phosphorylates only one of two serine residues in IκBα necessary for ubiquitination and degradation of IκBα. The degradation of IκBα exposes however, the nuclear localization signals on NF-kB, leading to its translocation to the nucleus, where it binds to specific promoters and activates transcription.

- PPP1R16A, also named Myosin phosphatase targeting subunit 3 (MYPT3) is a membrane located protein which having 524 amino acid residues, in which five Ankyrin repeats and a consensus PP1 binding site are located within the N-terminal 300 amino acid residues. The C-terminal region with 224 residues contains two possible Src homology 3 binding sites and a prenylation motif (CaaX). These structural features suggest that R16A could be a scaffold protein regulating protein-protein interactions as well as cellular signalling. (PMID: 18202305)

- RASSF7 is a member of a new Ras effector family characterise for the presence of a RA domain in their sequence. Although they interact either directly or indirectly with activated Ras, their role in mediating its biological effects remains unclear. What is clear is that they seem to modulate some of the growth inhibitory responses mediated by Ras and may serve as tumour suppressor genes. In fact, it is been described that members of the family are silenced in tumours by methylation of their promoters. (PMID: 17692468).

- TJP3, tight junction protein 3 (zona occludens 3) also known as MGC119546, ZO-3, ZO3 was found to be overexpressed in endometrial cancer primary tissue as compared to normal endometrial tissue by the microarray experiment described in Example 1. Further studies using RT-PCR demonstrated that TJP3 was overexpressed in primary endometrial cancer tissue as compared to normal endometrial tissue as described in Example 2. It was surprisingly found that TJP3 was overexpressed in samples obtained from uterine fluid (e.g., aspirates) from patients having endometrial cancer by the method described in Example 4. Example 5 shows that TJP3 can be combined with other biomarkers to give excellent predictive power for diagnosis of endometrial cancer.
- TJP3 (ZO-3) was first identified as a 130 kDa protein that coimmunoprecipitates with ZO-1. It is a member of the MAGUK proteins (MEMBRANE-associated guanylate kinase-like homologues). These proteins are implicated in the formation and maintenance of supramolecular complexes at specific areas of the cell surface called tight junctions. Tight junctions locate at the most apical part of lateral membranes of simple epithelial cells, and are considered to be involved in barrier and fence functions.
- Cloning and sequencing cDNAs encoding MAGUK proteins showed that all have three PDZ domains (PDZ1 to -3), one SH3 domain, and one guanylate kinase-like (GUK) domain in this order from their NH2 termini (PMID: 10966866). Among these domains, PDZ domains bind to COOH-terminal ends of various proteins, especially integral membrane proteins, most of which end in valine. Thus, MAGUKs can cross-link multiple integral membrane proteins at the cytoplasmic surface of plasma membranes to establish specialized membrane domains. ZO-3 has also been reported to associate with ZO-1, but not with ZO-2, although the domains responsible for ZO-3/ZO-1 interaction remain unidentified. ZO-3 was also shown to directly bind to the cytoplasmic domain of occludin (Haskins et al. 1998).

- EFEMP2 also known as FBLN4, MBP1, and UPH1 was found to be underexpressed in endometrial cancer primary tissue as compared to normal endometrial tissue by the microarray experiment described in Example 1. Further studies using RT-PCR demonstrated that EFEMP2 was underexpressed in primary endometrial cancer tissue as compared to normal endometrial tissue as described in Example 2. It was surprisingly found that EFEMP2 was underexpressed in samples obtained from uterine fluid (e.g., aspirates) from patients having endometrial cancer by the method described in Example 4. Example 5 shows that EFEMP2 can be combined with other biomarkers to give excellent predictive power for diagnosis of endometrial cancer.
